Save electricity costs
The NESS Smart Heater Pump can save on electricity costs in a huge way
Due to the present state-of-the-art, heat transfer oil heaters must be operated with the full flow rate, also when the full heat output is not required, and the heater works with partial load. This is now a problem of the past!
Electrical power consumption of a pump depends on the third
exponent of the fl ow rate and typically, much more oil is pumped
through the heater than what is required for safe operation of the
system.
Adding the optional NESS Smart HeaterPump, the load on the heater is monitored and the flow rate will be automatically set preventing the unnecessary waste of electricity.
Considering an average utilization of 80%, the operating costs for electricity can be reduced by approximately half. Also, the Smart Heaterpump is designed for maximum functional safety thanks to a redundant design. The Smart Heaterpump achieves the Safety Integrity Level 2 (SIL 2) and has been certified as a
minimum flow limiter according to DIN 4754-2.
The flow rate through a heat transfer oil heater is selected in a way that at full load, a desired temperature spread between flow and return flow is achieved. The specified film temperature of the heat transfer medium can never be exceeded in any operation. For this reason, the required minimum volume flow at full heater load is usually determined and then monitored. The NESS Smart Heaterpump continuously determines the required volume flow depending on performance required. However, if the heater is operated at partial load or the current flow temperature of the oil is lower, the film temperature in the heater is also
lower. The oil flow through the heater can be lowered without exceeding the maximum specified film temperature.
