₱95,000 a month back in your pocket.From day one.
For Philippine GMP pharmaceutical manufacturers and laboratories. The same Karnot platform that cools and dehumidifies your cleanroom air heats your CIP loop, your purified water and your AHU reheat coil — one electricity bill, no steam boiler running flat out, financed by the bank, paid for out of the saving. The heat your cleanroom AHU dumps to dehumidify today is the heat you pay the boiler to put straight back.
The cleanroom AHU cools the air to dry it. Then reheats it.
A GMP plant runs two opposing thermal jobs at the same time: the cleanroom AHU chills supply air below dew point to strip humidity to 45–55% RH, then reheats that same air back to a 20–22 °C setpoint — cooling and heating in series, paid for separately. Meanwhile CIP and purified water want 60–85 °C all shift long. Today those jobs run on separate bills — Meralco to chill and dump the heat, the steam boiler to put it straight back.
Cleanroom RH and temperature ARE your GMP licence — and your R404A chiller is the weak link
Cleanroom air must hold tight RH and temperature bands for product stability and audit — deep dehumidification, then reheat to setpoint. Most PH GMP plants run an ageing R404A chiller at COP ~2.8 with an F-gas phasedown clock on the asset register and service prices rising every year. Karnot iCOOL CO₂ holds the same cooling and dehumidification duty at COP 4.2 (Oak Ridge National Laboratory validated) — and the heat it removes is the heat your reheat coil and CIP loop need.
The steam boiler is your biggest controllable cost — and most of it is optional
CIP caustic and acid loops, purified-water heating, process hot water and cleanroom reheat (60–85 °C) run a steam boiler at roughly ₱2.1M/yr in LPG or diesel on a mid-size facility. But the heat your cleanroom dehumidification gives up, captured at the iCOOL CO₂ gas cooler at 75–90 °C, covers the reheat, CIP and process-water load. Only terminal sterilisation keeps a small electric steam top-up — we replace the utilities around the steriliser, not the sterilisation.
Chill the cleanroom. Bank the heat. Cut the steam bill.
A heat pump moves heat rather than creating it. When iCOOL cools and dehumidifies your cleanroom air and cools the cold chain, the heat removed is delivered to the hot side at 75–90 °C — exactly what the AHU reheat coil, the CIP loop and the purified-water system need. Your autoclaves, fillers and cleanroom kit stay — we replace the utilities around the steriliser, not the sterilisation.
iCOOL CO₂
Cleanroom dehumidification, process and cold chain at COP 4.2. The gas cooler delivers 75–90 °C hot water from the same compression cycle. A1 safety class — non-toxic, non-flammable, food/pharma-safe.
iHEAT R290
CIP, purified-water and reheat duty. Replaces the steam boiler for everything bar terminal sterilisation. Outdoor install, sealed 1.4 kg charge, EN 378 compliant — no flame on site.
iSTOR PCM
Thermal battery on both sides. Hot: recovered heat banked for CIP and reheat. Cold: cold storage and cleanroom ride through a PH brownout with zero compressor load. N+1 redundancy — the batch and cold chain survive the outage.
iSAVE + iVOLT
iSAVE meters every duty — audit-grade IPMVP M&V report monthly for GMP, your lender and a BERDE EE credit. iVOLT zero-export solar on the plant roof cuts the remaining grid draw a further 30–50%.
Mid-size GMP facility. A real number on every batch.
Modelled on a mid-size Philippine GMP manufacturing facility — cleanroom cool-and-reheat AHUs, CIP and purified water, process cooling, cold storage and an ultra-low cascade. The economics scale with cleanroom area and batch volume — a smaller lab divides down, a multi-line plant multiplies up.
| Annual figure · mid-size GMP | Today · boiler + old chiller | Karnot platform | You stop paying |
|---|---|---|---|
| Process heat (CIP + process + cleanroom reheat) | LPG/diesel steam boiler | iHEAT R290 + recovered heat | ₱1.6M/yr |
| Cleanroom cooling + cold storage | COP 2.8 · R404A | COP 4.2 · CO₂ GWP 1 | ₱680K/yr |
| Total energy bill (heat + cooling) | ~₱3.5M/yr | ~₱1.5M/yr | −57% / ~₱2.0M |
| Scope 1 + refrigerant exposure | ~65 tCO₂e + GWP 3,922 | GWP 1 & 3 · natural | ~75 tCO₂e/yr |
| Total investment (VAT-inc) | (already paid) | ~₱4.5M | 2.2 yr cash payback |
The cash flow. Plain and dull.
CAPEX of ~₱4.5M, financed under a green loan at ~7.5% p.a. over 7 years. The monthly saving (~₱167K) covers the monthly loan payment (~₱72K) more than twice over. Net cash in pocket from day one.
We don't guess the saving. We calculate your thermodynamic minimum.
Pinch analysis maps every hot stream in your plant (cleanroom dehumidification heat that must leave, condenser heat from the cold store) against every cold stream (CIP, purified water and cleanroom reheat that must heat) and computes the three numbers that define your energy performance. A GMP plant is the textbook case — the analysis practically writes itself.
The absolute least boiler energy your plant needs after maximum heat recovery. If your boiler burns more than this — and in every GMP plant we have surveyed, it does — the difference is pure waste.
The absolute least chiller energy required after recovery. Everything your chiller removes above this is dehumidification heat you paid to make and then paid again to throw away.
The GMP plant bottleneck temperature. Above it: heat deficit. Below it: heat surplus. A heat pump is the only utility that moves surplus heat from below the pinch to the deficit above it — which is why the saving is 57%, not 15%.
New to pinch analysis? We wrote the plain-English guide — no jargon, no PhD required, with worked composite curves explained in pictures. Then commission a Level 1 Energy Survey (₱90K, refunded in full on install) and we run the pinch study on your actual utility log.
You pay nothing up front. The bank does.
Three Philippine banks run green-loan programmes built for exactly this kind of project. The monthly saving covers the loan payment more than twice over. Net cash flow goes up from day one.
These are loans, not grants. Plus BOI Pioneer Income Tax Holiday under RA 11285 — energy-efficient manufacturing qualifies. Karnot files the loan, the BOI registration, the building permits and the monthly IPMVP M&V report your lender and GMP auditor want to see as part of project scope. You sign at the bank window, not before.

Frequently Asked Questions
How much can a Philippine pharmaceutical manufacturer save?
A modelled mid-size Philippine GMP manufacturing facility saves approximately ₱2.0M per year — a 57% reduction in the combined heating and cooling energy bill. Today's setup (an LPG/diesel steam boiler for CIP, purified water, process heat and cleanroom reheat plus an R404A chiller for cleanroom cooling and cold storage) costs about ₱3.5M/yr; the Karnot integrated platform delivers the same duties for about ₱1.5M/yr of electricity. With a 7-year green loan at ~7.5% p.a., the monthly saving (~₱167K) exceeds the loan payment (~₱72K), leaving roughly ₱95,000 net cash per month from day one. The economics scale with cleanroom area and batch volume.
How can the same machine chill the cleanroom and heat the CIP loop?
A heat pump moves heat rather than creating it. A GMP cleanroom AHU cools supply air below dew point to strip humidity to 45–55% RH, then reheats it back to a 20–22 °C setpoint. When Karnot iCOOL CO₂ does that dehumidification cooling, the heat removed is rejected at the CO₂ gas cooler at 75–90 °C — exactly the temperature the reheat coil, the CIP loop and the purified-water system need. Today that heat goes into a cooling tower while a steam boiler buys the same energy back. The Karnot platform transfers it across instead: chill the cleanroom, bank the heat, cut the steam bill. Your autoclaves, fillers and cleanroom kit stay — we replace the utilities around the steriliser, not the sterilisation itself.
Can a heat pump cover GMP process temperatures? What about sterilisation?
The iCOOL CO₂ gas cooler delivers 75–90 °C hot water and the iHEAT R290 cascade delivers 60–85 °C at COP 4.0+ in Philippine ambient — covering CIP loops, purified-water heating, process hot water and cleanroom AHU reheat, which together are roughly 80% of GMP thermal demand. Terminal sterilisation — autoclave or SIP at 121 °C — is the one duty above heat-pump reach and keeps a small electric steam top-up. We replace the utilities around the steriliser, not the sterilisation itself; the boiler stops running flat out and most of the combustion goes with it.
What is pinch analysis and why does it matter for my plant?
Pinch analysis maps every hot stream (cleanroom dehumidification heat that must leave, condenser heat from the cold store) against every cold stream (CIP, purified water and cleanroom reheat that must heat) and computes QHmin and QCmin — the absolute minimum heating and cooling your process needs after maximum heat recovery. Everything above that minimum is waste. In a GMP plant the pinch point sits around 35 °C, and a heat pump is the only utility that can move surplus heat from below the pinch to the deficit above it — which is why savings reach 57% rather than the 10–15% a heat-exchanger-only retrofit delivers. Start with the plain-English pinch guide, then commission a Level 1 Energy Survey (₱90K, refunded on install) and we run the pinch study on your actual utility log.
Is CO₂ refrigerant safe for a pharmaceutical facility?
Yes — CO₂ (R744) is an A1 safety class refrigerant: non-toxic, non-flammable and food/pharma-safe, with a GWP of 1 and no F-gas phasedown exposure. That matters next to a cleanroom and a cold chain holding finished product. Compare the legacy options: R404A and R134a chillers have GWP up to 3,922 with quota-driven service prices rising every year, and industrial ammonia is efficient but toxic — exclusion zones, specialist technicians, insurance loadings, a non-starter beside a cleanroom. Karnot iHEAT R290 (propane) sits outdoors with a sealed 1.4 kg charge under EN 378. Nothing on the asset register carries a phasedown date or an exclusion zone, and IQ/OQ/PQ-ready documentation comes with the install.
What happens to my cold chain and cleanroom during a brownout?
The iSTOR PCM thermal battery carries cold storage and cleanroom cooling through 8–12 hours of grid outage on stored cooling alone — no compressor, no generator — protecting finished product in the 2–8 °C cold chain and holding cleanroom conditions. The system is built with N+1 redundancy for validated, GMP-grade uptime, and the same battery banks recovered heat so CIP and reheat are ready on restart. iSAVE provides audit-grade IPMVP M&V evidence of that uptime and the energy performance for your GMP documentation.
Does this work for a research laboratory as well as a manufacturing plant?
Yes — a laboratory is the same pinch case at smaller scale. Labs run cleanroom and instrument cooling, ultra-low freezers and sample cold storage down to −20 to −80 °C on the cascade, while needing hot water for glasswash, autoclave feed and space conditioning. Karnot iCOOL CO₂ handles the cold side including ultra-low duties and the iHEAT R290 delivers the hot water at 60–85 °C, with iSTOR PCM protecting the freezers and sample store through a brownout. We size on your cleanroom area, freezer inventory and utility log; the economics divide down from the mid-size plant model.
What financing and incentives are available?
Three Philippine banks run green-loan programmes that fit GMP and laboratory CAPEX: DBP SEFP (~6.5–8% p.a., 70–80% LTV, industrial energy-efficiency priority), LandBank SEILP (~7% p.a., strong for regional pharma and life-science plants), and BPI SDF (~1–1.5% below standard SME rates). Most installs also qualify for BOI Pioneer status and an Income Tax Holiday under RA 11285 as energy-efficient manufacturing, and the audit-grade M&V supports a BERDE Energy Efficiency credit. Karnot files the loan application, the BOI registration, the building permits and the monthly IPMVP M&V report your lender and GMP auditor want — as part of project scope.
