Design
UNITHERM’S Small Industrial Boilers are conforming to the latest standards as laid down in the Indian Boiler regulations. The Unitherm fully automatic Small Industrial Boilers comprise of machine wound, specially designed concentric helical coils placed inside a sturdy M.S. double jacketed shell. The system comprises of three distinct passes of the flue gases in the Boiler & the non-pressurised heat recovery unit with heat optimiser constitutes the fourth pass, maximizing the efficiency.
Design available in all the fuel options & also with dual fuel Burner with a simple changeover switch.Highly efficient indigenous as well as imported Burner options available.

A special, anti drip design, high efficiency, imported burner of Riello (Italy) make with low noise blower and fuel oil pump ensure almost smokeless and silent operation and reduces the downtime and maintenance problems greatly. Due to it's unique design & efficient mixing of air & fuel, the combustion efficiency & hence the efficiency of the Boiler is also increased. The connected load is also much lower compared to any indigenous burner resulting in sizeable power savings.
The generously designed inner combustion chamber ensures large furnace volume and hence less heat load per unit volume, thereby increasing the life of the coil. The Safety controls and instrumentation provided ensure completely safe operation and provide Audio Visual alarm and cuts off the ignition system is case of abnormal operating conditions.

Salient  Features:

• Conforming to Small Industrial Boiler Regulations of IBR
• Substantially Lower Investment, compared to I.B.R. Boilers
• Instant steaming- full pressure of 12 Kg/Cm2 in less than five minutes.
• Four pass design with High efficiency, lower fuel costs.
• Non Pressurised Hot water pre-heater provided to minimize the flue gas losses.
• Sturdy construction, Long Life.
• Higher heating surface ensures complete conversion of heat produced.
• Large Furnace volume to ensure complete combustion of fuel fired.
• No certified Boiler attendant required, any matriculate person is permitted to operate the Boiler.
• Ready to use Packaged design, only service connections to be provided.
• Minimum foot print area and headroom requirement.

• Equipped with complete set of safety devices.   

Control Instrument And  Safeties:

• Fully automatic Operation
• Steam pressure switch for on/off operation of the Burner
• Low pressure switch to shut off the Burner in the event of low / no water flow in the coil.
• Temperature indicator cum controller with Burner interlock.
• Limit switch on blow down valve with Burner interlock – To avoid overheating of coil due to no flow, in case Blow down remains open
• Spring loaded IBR Steam safety valves - 2 Nos
• Light dependent resistor [flame sensor] to shut off the Burner in case of flame failure
