Heat Recovery
WRG accumulator
Environmental protection is achieved
through high-quality and efficency
All products can be manufactured
according to your requirements and needs
Operation
Cooling systems generate
heat. With the help of a heat
recovery system, this by-product will be no longer wasted,
but used reasonably.
You can utilize the otherwise
lost heat to produce hot wa-
ter and/or support the heating system. Therefore, less
expensive, conventional energy like oil, gas or electricity is
needed.
The heat recovery system
consists of a water tank and
internal heat exchanger. Within the heat exchanger, the
refrigerant will be liquefied.
The released heat raises the
temperature of the water
tank. Only minutes later, hot
water is available.
The cost savings pay off the heat recovery system
within a very short period of time
Specifics
Less environmental
burden
An important side effect of a
heat recovery system is the
lover environmental stress.
Utilizing the by-product heat significantly lowers the need for
environmentally harmful energy sources.
Reduction of operating
costs
Do you own an air conditioning system? Or do you plan
to purchase one? Are you interested in low operating costs?
An excellent opportunity to permanently lower your operating
costs is a heat reduction system
made by Unitec Energietechnik!

Examples – Heat recovery tank, 2.850 ltr., Height 3.820 mm, 3 stainless steel heat exchanger and 1 corrugated tube exchanger (picture left and middle below); Heat recovery tank, 3.600 ltr., Height 2.070 mm, 2 stainless steel heat exchanger und 2 integrated boiler (picture middle above and right).
Condensing
heat exchanger
Stainless steel heat exchanger,
suitable for refrigerant, designed
according to condensing temperature, purged with nitrogen,
soldered in with Schrader valves.
The heat exchanger use the superheat of the refrigerant (about
55 °C) for hot water production.
Going down the heat exchanger,
the refrigerant cools down to
condensation temperature transfering heat to support the heating system.
The heat recovery stands in line
with the efficiency of the refrigeration system.
Schrader valve: Pressurized system;
while assembling the connections, a simple
pressure test is possible.
