Few industries are as focused on avoiding unplanned downtime as data centers. To mitigate risk, data centers rely on multiple onsite generators that can be an unexpected source of high energy consumption. For over 80 years, Hotstart has been the industry leading engine heater manufacturer and the High Efficiency Engine Heater is the next evolution in coolant heating, keeping generators ready to start while reducing overall energy consumption during the generator’s idle hours.

Utilizing proven air-source heat pump technology, Hotstart’s High Efficiency Engine Heater maintains a generator’s ideal water jacket temperature during standby mode at a lower cost than a traditional engine heater. Generators 1MW and larger retrofitted with a heater can see savings of 20,000 – 40,000 kWh* or up to 75% annually per generator. High efficiency heaters are installed redundantly with an existing engine heater, ensuring overall data center resiliency.
