Safety testing of new products

In the following you can read more about the tests we perform when developing a new product

SAFETY

Frost protection of heat recovery units

EXHAUSTO has its own climate chamber for year-round testing, down to -35°C.  Here the control strategies which protect against ice formation in the heat recovery unit are tested (in practice this is most relevant for crossflow and counter flow heat exchangers). In most cases our crossflow and counter flow heat exchanger can tolerate temperature down to -50°C.

Motor testing

All new motor types, including associated control electronics (e.g. motor controllers for EC motors), are tested under extreme temperature conditions, including measurement of the motor windings temperature.

Water heating coils

Heating coils are tested so as to ensure optimum air and water distribution and to ensure no frost damage can occur at low outdoor temperatures in individual coil circuits.

Electrically heated heating coils

Heating coils are tested to ensure optimum air distribution and to ensure that the overheating protection works as intended – i.e. that the heat is disconnected in the event of an error function before a risk of damage or fire can occur.

Control system

All functions in EXHAUSTO's various types of control system are thoroughly tested when adding new facilities to the associated software.

Risk assessment

Before we launch a new product, we review it in detail with regard to its safety for fitter, technician and user. At the same time we check that the product manual gives the correct safety advice.
