The Fan Matrix – 2.75Kw 1 Speed Fan With Thermostat is a compact, 12V DC heat exchanger that combines a single‑speed cooling fan with an integrated thermostat to deliver reliable warmth exactly where you need it. Built for tight spaces, it moves heated coolant through a powerful 110 m3/h airflow, providing steady comfort without complex controls.

With ethylene glycol as the working fluid, this unit offers up to 2.75 kW of heating capacity. That level of output is ideal for mid‑sized vehicles, caravans, boats, or small cabins where space is at a premium but dependable warmth is non‑negotiable. The system is designed to be paired with your existing coolant loop, which helps maximize efficiency and minimize noise in occupied environments.

• 12V DC operation — straightforward power from vehicle batteries or fixed installations, optimized for mobile and off‑grid use.
• Low noise design — engineered for quiet operation so it won’t disrupt living or working spaces.
• 1‑speed fan with built‑in thermostat — simple, reliable temperature control that maintains your chosen comfort level without fiddling with multiple settings.
• Nominal airflow 110 m3/h — substantial air movement from a compact module, accelerating heat distribution.
• Heating capacity 2.75 kW (ethylene glycol) — robust warmth for medium‑sized spaces when paired with a compatible heater loop.
• Glycol connections Ø16 mm — standard sizing for quick, leak‑safe integration into common coolant hoses.
• Removable, heat‑resistant front panel — easy access for cleaning and servicing without disassembly.
• Maximum inner temperature 100°C — built to handle higher coolant temperatures safely within the system’s design limits.
• With AUTOTERM Flow series heater: up to 88°C attainable inside the loop — when paired with compatible heaters, the setup delivers predictable, controlled warmth.
• Arizona LN variant — marketed as a low‑noise water heat exchanger with fan for quieter operation in living or working spaces.

Who this is for: ideal for RVs, motorhomes, sailboats, and compact off‑grid cabins where space, weight, and reliability matter. It’s also a solid choice for installers building modular heating solutions for workshops or tiny homes that rely on a dedicated coolant loop. The combination of a thermostat, single‑speed fan, and removable front panel gives you precise control, minimal maintenance, and straightforward service access.

Practical use notes: ensure your system uses ethylene glycol and that your glycol lines are fitted to the 16 mm ports. Pair this heat exchanger with a compatible heater to maximize heating capacity, and place the unit where the front panel is accessible for routine cleaning to maintain optimal airflow. Compared with multi‑speed or fully electronic cooling fans, the 1‑speed, thermostat‑controlled design reduces wiring complexity and potential failure points—delivering dependable warmth with less hassle in mobile or remote installations.
