Mega Steam Singapore - Heat Pump Water Heater

Heat pump is a device in which the refrigerant R410A is continuously changing the shape from gas to liquid. It pumps out the solar energy from the air in the room and together with electrical energy consumed by compressor it gives out the total heating capacity which is accumulated in the water storage tank. Evaporator is an air-refrigerant heat exchanger. In the evaporator the refrigerant is vaporized at low pressure and relative low temperature. Because of vaporization the heat transfer form air to refrigerant starts. Vaporized refrigerant comes in the compressor where the pressure goes higher and also the temperature. From compressor the vaporized and high temperature steam goes in the condenser (refrigerant-water) where again the heat is transferred from refrigerant to water. The refrigerant is now in liquid shape idler high pressure. After it flows thought the expansion valve it reaches the basic shape and he process goes around again. The circuit is in process until the water temperature in the water storage tank reaches the set point.

Key Features of The Circulatic Vapor Steam Generator

• Rapid start up - from cold start to full load in five minutes.

• Easy access to burners - end mounted burner is simple to maintain.

• High quality steam - guaranteed 99% + dry steam.

• Low cost coil replacement - multiple coil design permits damaged coil replacement.

• Minimal soot problems - separate combustion chamber prevents coating coils with partially burned fuels.

• Minimum prepurge energy loss - smaller size unit allows proper prepurge in seconds.

• Low fuel requirements - air preheating and refractory lined chamber for complete combustion.

• Simplified fuel switching - only have to turn selector, no burner changes required.

• Quick response to load changes - cycle time of less than one minute.

• Minimum off-on cycling - turndown ratios up to 10-1 for handling wide range of loads.

• Complete line - nine sizes to permit proper selection for any application.

• Low installation costs - packaged, compact units require only 60% of floor space needed for firetube boilers.

• Long life with minimum maintenance - coil design pressure of 1000 psig result in thicker coil walls for longer life.

• Easy installation skid mounted assembly including control console.

• Optimum efficiency at any load - full modulation of water, air, fuel & output.

• Maximum safety - steam drum located outside of firing zone.
