GUANGZHOU BEDFORD ELECTRIC EQUIPMENT CO.,LTD.

 In the traditional air conditioning system, pump and exhauster working at full-speed all the year round. It regulate flux or flowing rate by throttling and backflow, lot of power waste on it.It gains obvious energy-saving effect when insert the inverter control system into the central air-conditioning system (such as control the cooling pumps,frozen pumps or the cooling fans), regulate the flux and pressure by inverter technology, in place of the way of control flux by valve opening.
  The cooling pump's inverter control has a various patterns, like pressure control, differential pressure control, temperature control,differential temperature control,etc.. Thereinto, temperature and differential temperature control is not only sensitive for surrounding temperature, but also weak on timeliness, it is not as good as pressure(differential pressure) control on stability and reliability. Differential pressure control is an variable flow control, it will confirms the system adapt to the variable air-conditioning load. It is reaction rapidly, little temperature and humidity influence, balance the system's supply and demands, do well in energy-saving, and so on.
With high quality, multi-function, low noise and strong commonality etc. characteristics, B605 series intelligent constant pressure water supply controller is suitable to full-automatic operation;
  1. Professional design based on users' needs, suitable for differential pressure control, simplicity of operation;
  2. According to the water condition to supply constant pressure water without manual operation after parameters were set correctly.
  3. Alarm automatically when fault occurred;
  4. Alternate running automatically in the multiple pump system, prolong the using life of pumps;
  5. Adapt to many kinds of input pressure signals;
  6. Can be connected to upper computer through RS485 communication function for centralized monitoring
