SANYO has been developing GHP VRF systems since 1980, during which time we have been committed to delivering ground-breaking technology. As a result, the commercial range of GHP VRF systems is leading the industry in the development of efficient and flexible systems, making them the natural choice for commercial projects, especially for those projects where power restrictions apply. As you would expect, all of our gas driven VRF systems have the highest reliability rates in the industry and a leading customer service program.
The new M Series of gas driven VRF systems offers increase efficiency and performance across the range. Now more powerful than ever before, it can connect to up to 48 indoor units.
Improvements include increased part load performance, reduced gas consumption with a Miller-cycle engine and reduced electrical consumption from using DC fan motors.
- Up to 71kW of cooling from a maximum running capacity o 5 AMPs
- Single phase power supply across the range
- The option of natural gas or LPG as its main power source
- Free hot water! A water heat exchanger to connect to domestic hot water systems 13-25 HP (2-pipe only)
- Option of DX or chilled water for indoor heat exchange
- Option to connect to third party AHU
- Reduced CO2 emissions
Power supply problems?
- If you are short of electrical power, gas heat pump could be the perfect solution:
- Runs on gas and just needs single phase supply
- Enables the building’s electrical power supply to be used for other critical electrical demands
- Reduces capital cost to upgrade power substations to run heating and cooling systems
- Reduces power loadings within a building especially during peak periods
- Electricity supply freed up for other uses such as IT servers, commercial refrigeration, manufacturing, lighting etc
High efficiency operation
13-25 HP models are equipped with a high-performance air exchanger and a newly developed refrigerant heat exchanger for high-efficiency operation, making them one of the most energy-efficient solutions on the market.
Lowest nitrogen oxide emissions
The GHP VRF systems have the lowest nitrogen oxide emissions, 66% below the standard. In a pioneering development, the SANYO GHP features a brand new lean burn combustion system that utilises air fuel ratio feedback control to reduce NOx emissions to an all time low.
Excellent economy
The SANYO GHP provides quick and powerful cooling / heating and increases delivery of heat into the space by the efficient recovery of heat from the engine cooling water, which is injected into the refrigerant circuit.
In addition, the use of engine waste heat ensures that our gas heat pump air conditioner requires no defrost cycle, therefore providing continuous 100% heating performance in severe weather conditions with an outside air temperature as low as -20°C. During cooling mode the rejected heat from the engine is available for use with in a DHW system and can supply up to 22 kW of hot water at 65 °C.
High performance
With its advanced heat exchanger design, this new GHP system offers improved efficiency and reduced running costs, which, coupled with improved engine management systems, have greatly improved the system COP rating.
Water chiller option
Our GHP system is also available with a water chiller option, which can be combined with individual outdoor units or as part of a DX chilled water mix of indoor units. The system can be operated via a BMS system or a SANYO supplied control panel, with chilled water set points from -15°C up to 15°C and heating set points up to 25°C to 55°C.
New electrical power generator model
The biggest breakthrough in recent GHP technology is the launch of the ECO G Power, which provides 4.0kW of power. That’s enough electricity to power 8 computers or 40 indoor units.
GHP Outdoor Heat Exchanger
- Integrated DX and hot water coil
- No defrost required
- Faster reaction to demand for heating
