Unit description The MTD2 heat pump optimized for geothermal systems are reversible units for heating, cooling and domestic hot water by external three-way valve (accessory). Both heat pumps MTD2 are suitable for traditional heating systemsand radiant panels. The latter, working with water at lower temperatures, ensure a higher yield and are a particularly appreciated for new buildings with low energy consumption that point on using renewable energy resources. The installation is greatly simplified through the integration of the group simply by connecting the unit to water plant and electricity so that it can be put into operation. Version - - Basic Features Structure and base in hot galvanised epoxy powder coated steel. High-efficiency plate exchangers in AISI 316 stainless steel with low pressure drops, fitted with heating element for frost protection. Hermetic scroll type compressors, equipped with the crankcase heater and thermal protection Case panels are insulated within low noise material for further improvement of silence Rubber vibration damper. Soft starter for 230V/1/50Hz units (ms) Phase sequence control relay for three phase models The water circuit comes complete with: Variable flow circulator for 0011÷0061 models and centrifugal variable flow pump for models 0071 ÷ 0121, plant side
