ZA1118A Radiator Training Panel Vocational Training Equipment Thermal Trainer
Description
The panel contains a pipe system with four radiators. Each radiator has an air bleed, a thermostatic valve and lockshield valve.
Rotameters indicate the flow rate through each individual radiator and for the entire system. Connections for cooling water make it possible to dissipate the heat supplied by the hot water. All water connections are made using quick-release couplings.

Plate Heat Exchanger Thermal Trainer Vocational Training Equipment
SR1158E Plate Heat Exchanger Thermal Trainer Vocational Training Equipment
I.Production profile
The key feature of plate heat exchangers is their compact design, in which optimum use is made of all of the material for heat transfer. The pressed in profile on the plates creates narrow flow channels, in which significant turbulence occurs. The turbulent flow allows effective heat transfer even with low flow rates and also has a self-cleaning effect. Plate heat exchangers are used in the food industry, offshore technology, refrigeration and domestic engineering.
II.Equipment feature
The SR1158E Plate Heat Exchanger is part of a series of units enabling experiments to be performed on different heat exchanger types. The experimental unit is ideally suited for investigating the functioning and behaviour of a plate heat exchanger in operation.
The plate heat exchanger is made up of profiled plates with water flowing through the spaces between them. The plates are soldered in such a way that two separate flow channels are formed. These are one “cold” and one “hot” flow channel, in an alternating arrangement. Part of the thermal energy of the hot water is transferred to the cold water. Valves on the supply unit are used to adjust the flow rates of hot and cold water. The supply hose can be reconnected using quick-release couplings, allowing the flow direction to be reversed. This allows parallel flow or counter flow operationspecification
