Unitherm VVT Series - Solid Fluid Heater

New VVT series multi pass Thermic fluid heater is designed to cater to the heat requirement of the process industrial where consistent temperature with fuel efficiency is utmost required.

Suitability for multi operation accessibility to the heat surface area and ample provision for ash removal makes VVT an ideal and attractive choice to the industries such as Textiles, Edible Oil Plants, Laminates, Plywood, Foods etc.

The Unitherm System is a forced circulation, fully automatic thermic fluid heater. The thermic fluid is circulated in a closed loop through heater and user equipment where the heat is dissipated through process. The same thermic fluid is recirculated through heater for reheating. The expansion and deaerator tanks ensure a pressureless and vapour free Unitherm System.

:: Features

Unique multi pass Thermic fluid heater comprises of 2 sets of heat exchanger

Larger heat transfer surface, adequate, fuel gas pass & velocity gives increased head transfer efficiency

Higher thermic fluid flow rates through the heater coils improves the life of the coil and thermic fluid heater to a great extent

Multiple ash collecting device at both the heat exchangers to collect almost all fly ash which can be removed during operation with great ease & thus provides:

Consistent efficiency & output

No choking of fuel gas passes and hence reduced down time for cleaning

No back firing due to choked flue gas passes.

:: The Safeties and Controls
