Low Temperature Hot Water Absorption Chiller (Single effect)

Use free heat from solar heat or waste hot water from incinerator therefore there is no additional cost from heat source, extremely energy saving unit.
Temperature of hot water: 90-80℃

Low Temperature Hot Water Absorption Chiller (Single effect)

High Temperature Hot Water Absorption Chiller

Use hot water gas engine (electricity generation)
Temperature of hot water must be higher than 140℃

Absorption Heat-pump

Absorption Heat-pump (Heat Amplifier Type)
Utilize waste hot water, excess steam or high temperature hot water to heat up low temperature water form 30-40℃ to high temperature hot water of 60-95℃, The heated up water can be used for production process.
Absorption Heat-pump (Heat Transformer Type)
Use low temperature waste heat to elevate the temperature which is higher than heat source. The heated water is used for process or flushing.

Absorption Heat-pump

Direct Exhaust Gas and Hot Water Type

Utilizing both exhaust gas and jacket water from gas engine, saving a lot of energy.
Multi energy heat source type: exhaust gas from diesel engine can also be used as a heat source for chiller.

Direct Exhaust Gas and Hot Water Type

Non-freezing Fluid Absorption Chiller (Brine chiller)

World first brine chiller with lithium bromide refrigerant which can produce -5℃ of non-freezing fluid.
Using water and lithium bromide solution which is not harmful to environment.
Chiller operates at under atmosphere pressure.
Waste heat can be used as heat source.
Reduced greatly the electricity cost.
