Pat Davey is CSE’s drives and motor specialist, helping electrical engineers with their individual project requirements. Pat recently assisted a local Building Management Services (BMS) engineer with his requirement for upgrading some drives used in an existing air conditioning installation for an end user who is in the Arts sector in London. After discussing the project, Pat suggested the ACH550 HVAC and subsequently supplied from stock a 1.5kW and 2 x 0.75kW drives. After the installation, the engineer contacted Pat to say that the installation had gone smoothly. Pat added “the engineer has been a customer for over year now, but phoned us afterwards to say how simple the ABB ACH550’s were to configure, programme and install compared with other drives he has used in the past”. The ABB ACH550 standard drive for HVAC is the first AC drive dedicated to the HVAC sector and is straightforward and simple to commission with the end user saving energy costs as it is a variable speed drive. If you would like to discuss your drives requirements with Pat and have a quote for a project, then please do not hesitate to contact him.
