Tenders Description & Specification for Trainer For Various Heat Exchangers
Trainer For Various Heat Exchangers
Examination and comparison of various heat exchanger types
Digital displays for temperature, pressure differences and flow rate
Control Interface Box and Data Acquisition Board part of system.
Flow rates adjustable via valves
Electromagnetic flow meter
Five different types of heat exchangers included in the scope of delivery
Finned heat exchanger with fan
Operating mode (parallel flow or counter flow) selectable via valves.
Technical Data Base service unit:
Stainless steel tank (30 l), equipped with:
Electric heating element (3000 W) with thermostat (70 °C), to heat the water, computer controlled.
Temperature sensor (“J” type) to measure the water temperature.
Stainless steel cover to avoid the contact with hot water. The cover should have a hole that allows to visualize the water level and also to stuff the tank.
Level switch to control the water level in the tank.
Draining water valve.
Centrifugal pump with speed control from computer, range: 0 – 3 l/min.
Two flow sensors, one for hot water and the other for cold water, range: 0.25 – 6.5 l/min.
Control valves for the cold and hot water.
Pressure regulator to avoid the introduction of too much pressure in the exchangers, tared at 0.6 bar.
Four flexible tubes to connect with the different exchangers.
Four ball valves that, depending on how manipulated, could give co-current or counter-current flux in the exchanger.
Two ball valves to control and drain the hot water of the base unit.
Dimensions: 1100 x 630 x 500 mm approx. (43.3 x 24.8 x 19.68 inches approx.).
Weight: 50 kg approx.
Ltekonline are the manufacturers of Trainer For Various Heat Exchangers used to demonstrate engineering principles in Engineering Colleges, Engineering Schools and Thermal Training Equipment for Engineering Teaching Lab in Universities
