STEAM BOILER

HEAVY DUTY CLASSIC 3-PASS STEAM BOILERS

Individual Thermal Solutions with Boldness and Care

The TT BOILERS type DJ & DJM steam boilers are developed in a rigid design especially for "heavy duty" operations. They are dedicated to applications where no compromise on quality are accepted - and where low pay-back time, and not cheap purchase price, are the key words.

Small & Medium-size Customised Boilers

Stabile and dry steam production with capacities up to 4,000 kg steam hour at working pressures from 1 - 20 bar (0.1 - 2 MPa).
High efficiencies of 90 - 91% ensure a supreme economy in operation. Beside this they are top insulated by mineral wool, which means a minimum heat loss from a cold surface.
NOx emission is minimised through a special geometry of the combustion chamber, and optimum utilisation of burner features.
Calm and stabile steam production, due to well calculated steam compartment, which also ensures a large steam buffer reserve during fluctuating consumptions.
Simple to operate and to maintain. The tubes bundles are easy accessible through a man hole, which also means general good access for inspection and cleaning of the inner parts of the boiler.
Finish of highest quality made by skilled and experienced boiler specialist, with a lot of details such as surfaces of stainless steel.
Customised with a lot of choices, which are based on the actual circumstances and local requirements.
The best of the best is obtained by choosing from the special DANA Line alternative. This is made by TT BOILERS and is the world's most exclusive boiler program.

TT BOILERS, type DJM

The smaller DJM are also classic steam boilers with oil, gas and dual fuel burners with optimum combustion economy in a 3-pass design.

Capacities from 125 - 400 kg/h at working pressures from 1 - 20 bar (0.1 - 2 MPa).

The smaller DJM offers the same features and advantages as the DJ, including a full 3-pass design. This type is an alternative to the steam generator dedicated those who prefer the classic steam boiler with a good steam buffer facility for varying operations. The DJM is less sensible to lack of feed water treatment compare to steam generators, and it has a slightly higher efficiency also.
