The country is short of cold storage — the President said so
"We really need to improve the supply chain, especially lowering the transport costs... And also, the cold storage, so the fish won't go bad, the other products harvested by our farmers won't go bad either."
Fish, meat, produce, dairy, vaccines — all of it needs cold rooms that do not exist yet. That makes cold storage one of the better businesses to be in. It also makes the running cost the difference between a good business and a struggling one.
Where the money goes in a cold store
Electricity is typically 25–35% of a Philippine cold store's total running cost. The compressors never sleep: food safety rules exist because the danger zone between 5 and 60 °C lets bacteria double every twenty minutes, so the plant runs every hour of every day, in some of the warmest ambient air on Earth.
Three things quietly inflate the bill:
- Old refrigerant plant. Systems on legacy HFC gas lose capacity in tropical heat and lean on the compressors to make it up.
- Demand spikes. Compressors starting together set a peak that your electricity provider bills you for all month.
- Heat thrown away. Every cold room rejects heat — most stores pay again to make hot water for washdown that the refrigeration plant could have given them free.
The bill is mostly the design, not the weather
By law, HFC refrigerants are being phased down in the Philippines — 80% gone by 2045 under the Kigali Amendment. An HFC plant keeps running, but the gas to refill it gets scarcer and pricier every year, until the system is not worth servicing.
Karnot iCOOL runs on CO₂ instead — a natural refrigerant that is exempt, abundant, and cheap. The result, against a typical HFC plant:
- Up to 50% lower refrigeration power bills. A ₱50,000-a-month refrigeration cost becomes about ₱25,000.
- Built for the tropics. The 2-stage compressor holds efficiency at ambient temperatures up to 45 °C — proven in over 10,000 installations.
- Free hot water. Heat recovery turns the rejected heat into 60–80 °C water for washdown and sanitation.
- Compliance built in. Documented temperature control for RA 10611 (Food Safety Act), DOH/FDA storage rules and NMIS meat inspection requirements.
Brownouts: a well-designed store rides through on thermal mass. Karnot pairs iCOOL with iSTOR thermal batteries, which hold the cold through an outage without running a compressor — the product stays in spec while the grid recovers.
What the fix pays — monthly cash, not someday
Most owners assume a plant upgrade means finding capital. Usually it means the opposite. Green-loan programmes from DBP, LandBank and BPI finance refrigeration upgrades over five years — and when the monthly power saving is larger than the monthly loan payment, your cash flow improves from the first month. These are loans, not grants, and the arithmetic only works if the saving is real — which is why we measure first.
Start with a free cooling load analysis: we log what your plant actually draws, size the replacement to your product and throughput, and give you the monthly numbers side by side.
Building new? Size the power first
The most expensive mistake in a new cold storage business is designing the building before the kilowatt-hours. Refrigeration sets your operating cost for the next twenty years. Decide the refrigerant, the heat recovery and the storage strategy first — then pour the concrete. Solar fits cold storage unusually well, because the cooling load peaks exactly when the sun does; we wrote that up in solar for cold storage.
Questions we get asked
How much electricity does a cold storage facility use in the Philippines?
Typically 25–35% of total running cost, because the compressors never sleep. A free cooling load analysis puts a precise number on yours.
Can I cut the bill without replacing the whole plant?
Often, yes. A survey finds where the kilowatt-hours go. An iMESH adiabatic retrofit boosts existing condensers 20–30% with a payback measured in weeks. The full CO₂ swap can come later.
What happens in a brownout?
Thermal mass carries a well-designed store through. iSTOR thermal batteries hold the cold without running the compressors.
Is CO₂ refrigeration proven in tropical heat?
Yes — over 10,000 installations on the same compressor platform, holding efficiency at up to 45 °C ambient.
Is my old refrigerant being banned?
HFCs are being phased down — 80% by 2045. Your plant keeps running, but every refill gets scarcer and pricier. CO₂ is exempt: still legal, still cheap, in 30 years.
