Hot Water Heaters :
Helical Coil Type
Espa hot water generators are designed to work in a closed circuit or open circuit depending and on the water specifications or process temperature.
This heater model can operate in a closed system or an open circuit system maximum temperature designed is 99°C.
This unit is helical coil 3 pass design, forced circulation, operating on Gas, light / heavy Oil or solid fuels. Efficiencies upto 94% NCV is possible consistently. All Hot water boilers are outside the purview of inspectorate of Boilers. Water as media for heating is safest for indirect process heating.
Some of the application are:
In order to maintain comfortable room temperatures in cold regions, a radiator circuit containing hot water from an Aquahot can be used.
- Spray Drying
The process involves hot air being blown into the spray dryer. Hot air can be generated by blowing air over a radiator circulating hot thermic fluid from an Aquahot. This process of drying is used in dairy, dyes, and some chemical industries.
Any surface before being painted or stored needs to undergo a pickling (metal cleaning) process. The chemicals in various pickling tanks are heated through coils circulating hot thermic fluid.
