Leminar Air Conditioning Company in conjunction with Hattersley Newman Henderson conducted a seminar on the ‘Application of Valves in Variable flow Cooling Systems’. Some 300 guests attended the seminar which discussed incorporating DPCV (Differential Pressure Control Valves) in designs. It was highlighted that the incorporation of DPCVs in cooling systems would enhance the overall efficiency of chiller and largely enhance the pump efficiency and therefore reduce power consumption considerably.
