Scanair heat pumps will maintain the temperature range from 28˚ C To + 65˚ C ˚ ± 1˚ C, capacity from 3Kw to 150Kw From10LPM to 300LPM with different flow capacity. Easy and practical to open side panels for servicing each plumbing, refrigeration accessories, electrical accessories. Compressors incorporate in a variety of safeguards that ensure durability including an internal pressure relief valve, motor temperature protections superior oil management functionality. These heats pumps are ozone friendly, packaged type have been designed for many years of trouble free operation. Scanair heat pumps ideal and most suitable for a wide spectrum of applications in industries like Swimming Pool, Household water heating, commercial building water heating, Industrial application Preheating, for Seed Drying, Food, Pharmaceutical Powder drying application etc.,

Heat pumps are more effective for heating than for cooling if the temperature difference is held equal.  This is because the compressor’s input energy is largely converted to useful heat when in heating mode, and is discharged along with the moved heat via the condenser.  But for cooling, the condenser is normally outdoors, and the compressor’s dissipated work is rejected rather than put to a useful purpose.

When comparing the performance of heat pumps, it is best to avoid the word “efficiency” which has a very specific thermodynamic definition.  The term coefficient of performance (COP) is used to describe the ratio of useful heat movement to work input.  Most vapor-compression heat pumps utilize electrically powered motors for their work input.  That is, one joule of electrical energy will cause a resistance heater to produce one joule of useful heat, while under ideal conditions, one joule of electrical energy can cause a heat pump to move much more than one joule of heat from a cooler place to a warmer place.  Sometimes this is inappropriately expressed as an efficiency value greater than 100%, as in the statement, Scanair heat pumps operate at up to 400% efficiency!”  This is incorrect term, since heat pump efficiency is measured in another way.  However it is correct to declare system efficiency of 400%.  The effective heating per watt of electric energy used can be up to 450% as much as resistance heating however, making this more an issue of semantics than science.

External energy is needed to drive the heat pump.  Theoretically, the total heat delivered by the heat pump is equal to the heat extracted from the heat source, plus the amount of drive energy supplied.  Electrically-driven heat pumps for heating buildings typically supply 100 KWh of heat with just 20 – 40 KWh of electricity.  Many industrial heat pumps can achieve even higher performance, and supply the same amount of heat with only 3 – 10 KWh of electricity.  Almost all heat pumps currently in operation are either based on a vapour compression.

In plumbing applications, a heat pump is used to heat or preheat water for swimming pools or domestic water heaters, commercial building water heating. The great majority of heat pumps work on the principle of the vapour compression cycle.  The main components in such a heat pump system are the compressor, the expansion valve and two heat ex-changers referred to as evaporator and condenser.  The components are connected to form a closed circuit.
