ZUWA, one of the leading edge manufacturers for HPAC equipment, is about to introduce a completely new device to decalcify plate heat exchangers and heat accumulators.
Calcifications up to 1 mm reduce the effectiveness of a heat exchanger by 10%. Thicker layers can cause a loss of up to 40%. In regions with calcareous water these components are to be decalcified in regular intervals.
In collaboration with Sanit Cleaners, a manufacturer of agents for cleaning tube systems, the ZUWA DESCAL was developed and tested. Similar to the ZUWA Solarcheck Mobile Center, the well known and approved solar collector filling station, the new device consists of trolley, pump, tank and hoses. In long term trials all components of the new member of the ZUWA product family have proofed their perfect compatibility with "Kalklöser" and "Citroplus" of Sanit.
At present further softeners based on formic acid and citric acid are being tested. A powerful ZUWA Impeller pump is the core of the station. Pump housing and fitting are made of stainless steel, impeller and shaft seal of acid resistant plastic. Separated from drinking water supply the agent circulates between the heat exchanger and the ZUWA DESCAL. With a pressure of up to four bar scale residues softened by the agent are washed out. Scale and dirt are collected in the tank on the device.
A filter on the inlet of the pump keeps loose particles from returning through the pump back into the system. The high flow rate of the pumps (30, alternatively 60 litres per minute) care for a perfect finish. The flushing process is continued till the liquid is free of any scale remainders which can be observed through the transparent hose.
Working with the ZUWA DESCAL is a clean job. A pressure valve at the pump outlet makes sure the filling hose is not under pressure when removed from the fitting, no acid leaves the device. In contrast to other pumps ZUWA impeller pumps run almost completely empty. The pump housing is opened easily for cleaning. The tank can be removed in no time from the trolley for cleaning or replacing in case various tanks are supposed to be used with different liquids.
See it live at the ISH Frankfurt, March 10 till March 14., 2009 at our booth E02 in Hall 9.1 or C96, Hall 6.3
