The Wacker Neuson Thermostat Adapter BM2 is a genuine OEM component designed for the HI series indirect air heaters, including the HI 110D, HI 110HD D, HI 200D, HI 200HD D, HI 300D, HI 300HD D, and HI 400HD D and HI 400HD G models. As a direct factory replacement, part ensures the thermostat assembly seats and seals exactly as the original, with no guesswork at installation. Sourced directly from Wacker Neuson, this adapter carries the full OEM quality assurance that technicians and contractors rely on to keep indirect heating equipment running through demanding cold-weather operations.
Key Features
- OEM-Spec Thermal Interface: — Manufactured to the same dimensional and material tolerances as the original, ensuring the thermostat seats correctly and regulates coolant flow as intended by Wacker Neuson engineers.
- Drop-In Replacement Fit: — Connects directly to the existing thermostat housing on compatible HI series heaters, using the original mounting points and sealing surfaces for a straightforward swap.
- Broad HI Series Coverage: — Compatible across the HI 110D, HI 200D, HI 300D diesel indirect heaters and the HD variants — HI 110HD D, HI 200HD D, HI 300HD D, HI 400HD D, and HI 400HD G — covering a wide range of Wacker Neuson indirect air heating equipment.
- Sustained Heating Output: — A correctly functioning thermostat adapter keeps coolant temperature regulation on track, allowing the heater to deliver consistent, rated heat output in cold-weather jobsite conditions.
- Fuel System Safety Compliance: — Proper thermostat function in a diesel indirect heater directly affects combustion cycle management; using a genuine OEM adapter ensures temperature-related safety thresholds are maintained as designed.
- Genuine Wacker Neuson Part: — Supplied as original equipment under part number 5200007098, backed by Wacker Neuson's OEM quality assurance for professional-grade reliability.
The thermostat adapter acts as the mounting and sealing interface between the thermostat element and the heater's coolant circuit in Wacker Neuson indirect air heaters. It holds the thermostat in the correct position so it can accurately sense coolant temperature and regulate flow between the burner heat exchanger and the output airstream. When this adapter is cracked, corroded, or improperly seated, coolant can bypass the thermostat unpredictably — causing the heater to overheat, underperform, or trigger safety shutdowns during operation.
