Positioning of heating equipment in the bath (gas-fired immersion heater):
Possibility of fitting in existing baths. Autonomy of different processes. Substitute of all or part of centralised heating systems (support of an overloaded installation).
The ease of installation enables better autonomy in different processes, where efficiency is increased and energy costs are reduced.
No loss of time or energy in order to increase the temperature. The only thermal inertia is linked to the volume of the bath. There is a noticeable improvement in the production of hot water in existing electric water-heating tanks by installing a gas immersion heater on a free manhole. The quality of components provides a degree of simplicity and comfort.
Thanks to the exceptional output of the compact immersion tube (more than 93% of Net Calorific Value), energy costs can be reduced by 20% to 50%. Furthermore, its direct installation in the bath neutralises losses in energy.
The equipment is made up of 3 sub-assemblies:
1 - The burner uses a total pre-mixture of air/gas. The homogeneity of the flame and the high circulation speed of combustion products ensure high levels of efficiency (95% of NCV and up to 105% in certain cases), an optimal combustion hygiene and a reduced noise level.
2 - The heat exchanger or coil has a developed length and a tube diameter corresponding to the power to be transmitted. Very compact in design, it has a geometry which can adapt to any shape of tank. It is manufactured in a stainless steel grade adapted to the type of bath to be heated up.
3 - The air/gas pre-mixing line is made up of an air fan and a set of solenoid valves enclosed in a stainless steel sheet housing. The whole unit is controlled by means of a control panel.
Food processing industry:
- Tunnel pasteurisers, industrial cookers, blanchers, sterilisers, industrial washers, CIP station tanks, continuous deep fryers, 'sous-vide' or 'under vacuum' cooking, pig and poultry scalders, production of domestic hot water, production of floor cleaning water, wort boiling in mini breweries.
Surface treatment industry:
- Degreasing, pickling, rinsing, phosphating, passivating, anodising baths, washing tunnels (industrial washers)
- Wool washing, dye baths, production of superheated water.
Market gardening industry:
- Heating greenhouses with CO2 production
The heat input range extends from 40 to 1500 kW.
Until recently, the use of low heat input compact immersion tubes represented a relatively high cost in terms of investment. THERMIGAS has developed a burner almost 9 years ago with a heat input between 40 and 70 kW at an attractive cost hence solving those problems relating to low-heat input requirements.
