Dimplex heat pumps - WF Senate

High temperatureground sourceheat pumpsSI TEHThe Dimplex SI TEH range of high temperatureground source heat pumps provide variablewater flow temperatures up to 70°C, providinga solution for buildings with high temperatureheating systems (radiators) or where hightemperature hot water storage is required.Available in 20kW and 40kW options, bothmodels utilise the WPM2007 heat pumpmanager, allowing independent control overmultiple heating circuits at differing flowtemperatures.Both models incorporate twin compressors,enabling them to flexibly and efficiently adaptto fluctuating heat demand by automaticallyswitching between single and dual compressormodes depending on the outside temperatureand heat demand of the building.SI 20 TEHRange features• Nominal heating capacities of 20kW and 40kW.• Variable heating water flow temperatures from35°C – 70°C with weather compensation.• Twin compressors for higher capacity output.• Intelligent switching between single and dualcompressor modes, maximising efficiency andcompressor duty cycle.• WPM2007 heat pump manager with removablecontrol panel.• Suitable for use with underfloor heating or radiatorsystems and to provide domestic hot water atstored water temperatures of up to to 60°C.• Three phase electrical connection, with electronicsoft start to reduce start current loads.• Able to use ground water as a heat source withthe addition of an intermediate heat exchanger.• Matching 400 litre domestic hot water cylinder.SI 40 TEHModel SI 20 TEH SI 40 TEHConnection Voltage (V) 400 400Maximum flow temp (°C) 70 70Heat output B0/W35(kW)1 Compressor 11.5 17.42 Compressors 21.4 34.2CoP B0/W351 Compressor 4.6 4.12 Compressors 4.4 4.1Please see page 52 for full technical specifications.SI TEH33
