CLV Single Fluid Electric Heating System

The CLV is a complete system designed to preheat coolant,  eliminate idling, save fuel and reduce wear.

HOTSTART's CLV Single Fluid Electrical Engine Heater is designed to preheat coolant to heat the prime movers of locomotives as well as diesel and gas engines of generators, marine vessels and mining equipment. For locomotive or machinery applications, the heating system may be connected to shore power in the locomotive yard or equipment bays when not in use. For marine vessels, power is supplied by shore power when docked or by on-board generators while at sea. 

The CLV is a complete heating system, circulating heated coolant throughout the engine's water jacket, eliminating unnecessary idling, saving fuel and reducing wear and tear from cold starts. The CLV heating system is capable of heating engines up to 300 L displacement and features accurate PT-100 temperature sensors, allowing users to easily adjust the desired temperature.

The CLV control box is equipped with convenient side-mounted controls and a removable lid to maximize possible installation locations where equipment space is at a premium. To further minimize overall footprint, modular CLV systems are available, allowing the pump and tank to be installed near the engine plumbing ports while the control box is placed in a location convenient for operator access and monitoring.

Not intended for hazardous locations.
