The Hydronic 5 from Espar Heater Systems is an engine preheating solution for off-highway applications featuring automatic, programmable heat regulation. The independent, fuel-operated heater has an integrated water pump combined into the engine's cooling system. A built-in pump draws fuel from 0.08 to 0.16 gal/h (0.3 to 0.6 L/h) from the application's tank reservoir. Measuring 9.75 x 3.5 x 6.3 in (250 x 90 x 160 mm) with a mass of 6.3 lb (3 kg), the heater offers a seven-day programmable timer with built-in fault code retrieval. The Hydronic 5 is capable of defrosting the windshield and prewarming the bunk prior to engine start-up by using an internal blower with a relay switch. The unit also prevents cold starts by preheating the engine during shutdown. Benefits include improved efficiency and maintenance and an increase in operator efficiency, comfort, and safety.
