5. ELECTRICAL HEAT UNITS :FHU36

Product catalog summary

Technical Description
The FHU36 is a heating unit with a power capacity of 36 kW and a motor power of 3 kW for the circulation fan. It operates on a supply voltage of 3x400/230 Volt, 50 Hz/63A, and can reach temperatures up to 100°C. The unit dimensions are 900x1500x1050 mm. It features an insulated housing with a circulation fan, motor, heating elements, and a control cabinet, all mounted on wheels for mobility. The air temperature is regulated by a sensor connected to the control cabinet, and an overheating circuit breaker is included for safety.

Safety
Users must handle hot goods carefully to avoid burns and should not leave them unattended. The unit should be operated by skilled personnel, and local fire safety regulations must be followed. The FHU36 should be placed on a fireproof foundation and kept away from flammable materials. Proper connection of pipes is essential to prevent injuries, and the unit should be protected from weather when used outdoors.

Temperature Controller
The FHU36 uses a BTC 9100 digital temperature controller to regulate the outlet air temperature. The controller displays the actual and desired temperatures and adjusts the output through a contactor. Users should exercise caution when changing parameters to avoid malfunction or damage.

Instrumentation
The unit includes a temperature controller and alarms for overheating and motor issues. The overheat alarm requires cooling and manual reset, while a motor alarm indicates a circuit breaker release. A sensor break will prevent the unit from generating heat until resolved.

Operation
To operate the FHU36, assemble it in the curing space, connect the power cable, and place the temperature sensor. Turn on the main switch, check the fan rotation, and set the desired temperature using the controller. The unit will maintain the set temperature by cycling the heater package on and off.

• Remember that goods can be hot and can give serious burns if not handled correctly. Do not leave hot goods unattended without giving notice, by marking with a sign or similar. Alternatively cover the goods with an appropriate cover (ex. glass fiber cover). Establish or maintain working routines that are suited for the FLV operation and minimize handling risks. • Be aware of possible fire risk with heated object. • The FHU36 hardware and electronics must be supervised and repaired by skilled personnel (personnel with proper knowledge or certification). Ensure that the involved personnel receive...

3. Temperature Controller The outlet air temperature is regulated by a digital temperature controller, BTC 9100. The red display shows actual temperature (Process Value) in the oven and green display shows the desired temperature (Setpoint). The controller regulates the effect (output) through a contactor. Value changes are made by pressing the symbol Increase arrow (Up key) or Decrease arrow (Down key). Left symbol ”Scroll Key” is used for configuring regulator parameters. Observe great caution when changing unit parameters. Incorrect programming (setup) can cause unit malfunction, incorrect...

Assemble the unit to the space for curing. Connect main power cable. Place temperature sensor in the outlet of the unit and connect to control unit. Put “Main Switch” in position 1(ON). Control fan wing rotation direction (see arrow). Exchange two power cords to the unit if the rotation direction is incorrect. Set desired temperature on the temperature controller with keys up/down to increase/decrease value. The red indicator “OP1” is lit when the controller is heating up the unit. When desired temperature is reached, the controller switches the heater package power on/off to maintain the temperature....
