For years we struggled with our marine refrigeration problems. We searched for a solution and a system that seemed to be the right fit for our offshore sailing aspirations. But we couldn’t find an energy efficient and reliable system on the market.
That’s why we’ve designed the ColdEh marine refrigeration system that we believe is ‘bullet-proof’. Our system is built by sailors for sailors. You can depend on it (even if you are far, far away like so many people are when they encounter catastrophic refrigeration ‘melt-downs’!).
Here are 5 typical marine refrigeration system problems (do they sound familiar?)… and how we’ve built ColdEh to avoid them:
Problem # 1: Water-cooled systems that stop cooling!
If you have a water-cooled system, the water flow can become restricted, and requires constant cleaning of sea strainers
The ColdEh Solution:
ColdEh solves this one with air-cooling. No sea strainers (or constant maintenance) required! And that means no opportunity for the system to become blocked and inoperable.
Problem # 2: Algae Interference
Keel cooled systems are very susceptible to marine growth and loss of performance when the boat is "parked" (when you just want spend some time at dock or at anchor and don’t want to go bottom-scrubbing).
The ColdEh Solution:
With the ColdEh system, ‘fuzzy bottom’ does not interfere with refrigeration efficiency or operation. (what a relief)
Problem # 3: No refrigeration on the dry land
Water-cooled systems cannot operate on the hard, which eliminates cold food storage during haul-out periods for boat maintenance. And there is the added nuisance of using up cold-stores ahead of time, carting blocks of ice as an intermediary cold source, and not having ice cubes just when hard work demands a cool drink!
The ColdEh Solution:
ColdEh systems don’t need to be in water to operate. That simplifies ‘dry-dock’ time immensely.
Problem # 4: Another thru-hull?
Installing a water-cooled system requires a thru-hull (which of course must be regularly maintained). For new-builds or for newly fitting a refrigeration system into your vessel, you may need to create a new thru-hull which is complicated , it also entails the cost of a lift out!
The ColdEh Solution:
ColdEh does not require a thru-hull. Enough said.
Problem # 5: Warm water and hot weather
Warm water-temperatures increase the energy consumption of water-cooled and keel-cooled systems. And in hot weather, typical water and air-cooled marine refrigeration systems react by slowing refrigerant flow so they run constantly, using more energy. Just when you need maximum cooling, these systems begin to struggle under the load. And, solar-powered operation (especially during reduced daylight hours) may be impossible because of the increased power draw.
The ColdEh Solution:
With energy efficiency as our primary goal, we developed the system to operate with low-draw regardless of ambient temperature conditions. So, if it rains for days or the water is extremely warm, or the mercury soars, you can depend on excellent refrigeration performance that does not increase its energy use (making it idea for solar-powered operations).
