The PEREGRINE DS and DSW-type 230V engine coolant heaters are specified where space is limited but performance cannot be compromised. Developed as the short-canister alternative to the DL-type, they provide a practical solution for restricted-height installations without sacrificing heating efficiency or reliability.

Engineered with thermostatic control and a single, low surface-watts density element, the DS range is designed to maintain stable coolant temperatures, helping to ensure fast, dependable engine starts. By circulating warmed coolant through the engine block, these heaters reduce fuel consumption, emissions and engine wear, particularly in engines that must remain on standby for long periods. These units are fitted as standard with our adjustable digital thermostats, allowing precise temperature control to suit the application.

Installation flexibility is a key design consideration. The compact canister allows the heater to be fitted vertically or horizontally, making integration straightforward for OEMs, engineers and maintenance teams, whether for new builds or retrofit applications. The DSW-Type offers a weatherproof option where additional environmental protection is required.

For duty-critical applications such as fire pumps and standby power generation, reliability is essential. The DS and DSW heaters are built to deliver consistent performance, providing reassurance that equipment will start and operate as required when it matters most.

Manufactured with a long-lasting steel body and built to exacting standards, Peregrine coolant heaters reflect a commitment to quality, durability and trusted engineering.

Designed for confined spaces. Built for reliability. Trusted for critical start-up performance.
