SIH TU

Description

The SIH range of ground source heat pumps are able to meet heat loads from 4–90 kW with a single unit and if banked together can achieve outputs up to 1170 kW. The high efficiency design delivers excellent seasonal performance which helps to meet building regulations and reduce running costs.

Features and benefits:

  • High temperature and high output ground source heat pump with thermostatic expansion valve and integrated WPM 2007 plus heat pump manager. Designed for indoor installation with service access from the front and no requirement for side access.
  • Two scroll compressors flexibly and efficiently adapt to fluctuating heat demand with intelligent load switching between compressors to maximize compressor life.
  • Reduced operational noise through the use of a free-swinging compressor base plate allowing direct connection to the heating system.
  • Integrated soft starter and relay for brine circulating pump, flow and return sensors, external sensor and dirt filter for brine circuit included in the scope of supply. SZB Brine package and circulation pumps must be ordered separately.
  • CE marked.
