Rheinmetall Receives Multi-Million Euro Orders for Coolant Control Valves in Fuel Cell-Powered Trucks

Rheinmetall Receives Multi-Million Euro Orders for Coolant Control Valves in Fuel Cell-Powered Trucks

(IN BRIEF) Rheinmetall AG, a technology enterprise, has secured significant orders in the mid-two-digit million-euro range from a major international truckmaker for coolant control valves to be used in fuel cell-powered trucks. The orders include electronic thermostatic valves and coolant valves, crucial for maintaining precise coolant temperature regulation in fuel cell systems. The new valves offer improved accuracy compared to traditional thermostats, ensuring the longevity of fuel cells. They also allow precise adjustment of coolant flow, addressing potential issues arising from low temperatures. Rheinmetall’s expertise in hydrogen technology and fuel cell-related products positions the company as a key player in the development of CO2-neutral drive solutions for heavy transport trucks. Initial deliveries are expected in 2024, with full-scale production starting in 2028.

(PRESS RELEASE) DÜSSELDORF, 22-Sep-2023 — /EuropaWire/ — The technology enterprise Rheinmetall AG continues to successfully grow its business in fuel cell-related products. One of the biggest international truckmakers has placed two first-ever orders with the Group for coolant control valves for use in fuel cell-powered trucks. The fuel cell is a crucially important CO2-neutral drive solution, especially for heavy transport trucks.

The aggregate value of the orders is in the mid-two-digit million-euro range. The first lot is due to be delivered in 2024 for initial installation in several hundred trucks. Full-scale production is set to commence in 2028.

An electronic thermostatic valve (3/2-way valve) and an electronic coolant valve (2/2-way valve) were ordered for use in the cooling circuit of a fuel cell.

High coolant temperatures have a strongly negative impact on the longevity of a fuel cell. Representing a key improvement,
Rheinmetall’s newly developed valves assure a highly dynamic yet very exact regulation of the coolant temperature. Previously used thermostats with expansion elements are subject to hysteresis, making them both sluggish and inexact.

Temperatures that are too low can also have a negative effect on fuel cells. Rheinmetall valves – in accordance with individual application requirements – enable freely selectable, precise setting of the required coolant flow. The electronic actuator used here is a tried-and-tested smart truck actuator with CAN bus-capable electronics and an electronically commutated motor.

Moreover, the components’ extremely low loss of coolant pressure, coupled with negligible leakage and an innovative valve design enabling an optimum installation space connection and compact packaging, were also important in winning over the customer.

Rheinmetall has developed an extensive array of fuel cell-related products. The Group has been actively involved in hydrogen technology for almost twenty years now and can thus draw on extensive experience.
