Boiling Heat Transfer Unit Manufacturer,Supplier and Exporter in India
Product Code : EL-MLE-13270
Jlab Export is a leading Boiling Heat Transfer Unit Manufacturer,and suppliers in India
Boiling Heat Transfer Unit (code EL-MLE-13270) is a demonstration unit that makes boiling and evaporation visible inside a transparent pressure vessel filled with R1233zd refrigerant. A heating element of up to 300 W boils the liquid, and a coiled copper tube carrying cooling water condenses the vapour, so the process runs continuously in the closed vessel. In Ambala, India, JLab builds the complete boiling unit.

From Convection to Nucleate Boiling
At low heater power, heat passes from the element into the liquid by natural convection and no bubbles form on it. As the power rises, vapour bubbles start at points on the heating surface and leave it in growing numbers: this is nucleate boiling, in which the heat flux climbs steeply for a small rise in surface temperature. The pressure, temperature and flow sensors show each operating point on the digital display, so the onset of boiling can be matched to the heater power.
Condensation, Pressure and Cooling Water
The vapour condenses on the cooled copper coil and drips back, so the vessel pressure settles where heater power and cooling balance; raising the cooling water flow lowers the pressure and with it the boiling temperature. Water comes from the lab supply or from a separate water chiller that keeps it at 16 °C or below, and a 4 bar safety valve with an adjustable pressure switch protects the vessel against overpressure.
Other Boiling and Condensation Apparatus
- Critical Heat Flux Apparatus — electrically heated test wire in water, showing pool boiling regimes to burnout.
- Marcet Boiler — stainless steel boiler relating steam pressure to temperature as water is heated.
- Dropwise and Filmwise Condensation Apparatus — dropwise and film-wise condensation on copper tubes inside a glass cylinder.
The unit is listed in Mechatronics Lab Equipments, part of Mechanical Engineering Lab Equipment.
