How are ColdEh™energy savings calculated*?

ColdEh™ calculates estimated energy savings by comparing test system run-time rates and the average rates noted by leading refrigeration system providers. Our rigorous tests have been performed in 70F/21C and 120F/49C ambient environments. The result? 30% energy consumption savings.

What makes ColdEh systems energy efficient?

ColdEh Systems have more copper than any other marine refrigeration.

Copper is first choice for high thermal conductivity, operating almost 90% more efficient than aluminum when transferring heat from the air to refrigerant (and 30X better than stainless steel).

That is why ColdEh’s exclusive custom-copper evaporator plate design is a refrigeration heat transfer platform that removes heat more efficiently, so your system cools down quickly and stays cool, saving you energy (perfect for solar applications).

How do changing weather and ambient temperature condition effect ColdEh™energy use?

As the ambient temperature increases your ColdEh™ refrigeration system automatically increases the rate it exchanges heat with its surroundings. The unique high-efficiency copper components work with a Thermostatic Expansion Valve (TXV) to deliver consistent performance even as temperatures soar and your foodstuffs load and use increase.

It takes very little energy to maintain constant compartment temperature.

The air-cooled condensing unit runs quietly and efficiently, eliminating the power draw experienced

with auxiliary pumps found in water-cooled refrigeration systems.

What is the cost of energy inefficiency?

Price is a simple number. How much money do I need to hand you to get this thing?

Cost is more relevant, more real and more complicated.

Cost is what you have to give up to get the convenience of safe food storage.

Cost is how much power it takes to feed the system.

Cost is how much time, money and intrusion it takes to install the system.

Cost is how much effort it takes to care for it, maintain it and troubleshoot it.

Cost is my lack of focus because of noise and heat it makes.

Cost is the externalities, the side effects.Just about every time, cost matters more than price.

ColdEh refrigeration systems do not have the lowest price.

But we work to ensure that they have the lowest cost to you.

And that is our work to deliver the most energy-efficient systems for you.
