Emergency Generator Heating Solution for heating backup emergency generators

Our GTS division has over 25 years of experience with customers in every industry where emergency diesel power systems are needed: water and waste water treatment plants, hospitals, prisons, data centers, tall buildings, airports, etc.

We have installed thousands of heat pumps which continue to provide our customers with a redundant heating source for our emergency diesel generators, while saving thousands of dollars annually on each generator — all while reducing greenhouse emissions.

Benefits of our Heat Pump Technology

  • Life expectancy of over 15 years
  • Air-Conditioned air output for switchgear rooms, reducing cooling loads
  • Eliminates cost of replacing block heaters, $1000 or more per failure
  • As a rule of thumb, our heating system will reduce electric consumption by over 15,000 kWh per Megawatt of engine capacity

The Process

  • The patented process GTS heat pump is installed in series with existing block heaters.
  • The patented process GTS heat pump comes equipped with a dual control thermostat and two normally open contacts.
  • The existing block heaters are wired to the secondary contactor. They are now controlled by the second stage of the thermostat.

The thermostat maintains the engine block at the desired temperature, cycling the heat pump on and off.

The existing block heaters only operate if the heat pump fails, and the temperature drifts down to the set point for the block heaters. At this point an alarm is activated on the heat pump, and an agent will repair or replace the heat pump within 48-hours. In the meantime, the engine is kept hot as it always has been kept, through the use of the existing block heaters.

Heat pumps also last a long time. A 2005 study reported in Air Conditioning/Heating/Refrigeration News, called Increasing Consumer Confidence in Heat Pumps, found that the observed median service life of a heat pump-when removed because of failure-was 26 years.

Why Heat Your Diesel Engines in Standby Mode?

  • To insure that the engine will start
  • To prevent 'cold-start wear,' and the subsequent catastrophic failure, by expanding the dissimilar metals to proper operating tolerances.

All emergency generators share one thing in common, and that is that they must be kept at a constant “hot” temperature to insure a safe and reliable split-second start-up, and to prevent ‘cold start wear’. The company’s product does this at 1/5 to 1/6 the cost of any current or competing technology and is protected by a patent (#RE 33,051).

​Diesel engines do not have spark plugs. Diesel engine operation is based on the compression ignition principle, which means the temperature of the air in the cylinder increases in direct proportion to the compression ratio (i.e. if the compression ratio is 18:1, the air is compressed eighteenfold, and the temperature increase is also eighteenfold), increasing the temperature to obtain the minimum temperature necessary to ignite the diesel fuel
