Profile: Conder Environmental Solutions Ltd. is a manufacturer of sewage treatment systems. Our product line includes separators, sewage treatment plants, booster sets, and expansion tanks. Our booster sets include Combipress® series which are pressurization units consisting of two or more pumps with controls, supplied pre-assembled, and ready for installation. They are available with a choice of two alternative control systems: active standby, and total standby. In this mode, the unit monitors demand, and automatically starts one or more of the standby pumps as required to keep up with changes in water use. This system avoids having large pumps running at times of low demand, and therefore offers significant energy savings. Our SolarWave™ expansion tanks are designed to control the expansion and contraction of solar thermal transfer fluids in solar heating systems. The SolarWave™ series is intended for use on the solar liquid loop of indirect thermal transfer systems.
