HWT-800 : Hot water tank 800 liters

There is necessary to have enough of drinking hot water available during beer production process. Hot water is used for mixing malt mash in water in process production of wort, for showering of wort during the wort filtration process, for cleaning and sanitizing of the brewhouse and other vessels etc.

The hot water tank HWT-800 (boiler) is equipped with a water pumping unit. It is designed for storage of 800 liters preheated water from the first cooling stage and following heating up to 80°C. The container is made of material  AISI 316L, DIN 17 349, AKV extra 2.

Four variants of heating system :

• SH – Steam heating system – water is heated with hot steam (requires an external hot steam generator). Includes the water pressure station.
• EH – Electric heating system – water is heated with electric heating spirals. Includes the water pressure station.
• BH – Both heating systems – both electric and steam heating (requires an external hot steam generator). Includes the water pressure station.
• NH – Without a heating system – only for storage of externally heated water without any own heating system

Parameters:

• Total capacity 850 l
• Diameter with insulation 800 mm
• Weight 118 kg
• Input power of heating element 3 500 W
• Input power of pumping unit 360W
• Overall height 1 800 mm

Accessories:

• Oval manhole 340*420 mm
• Inlet and outlet armature DN 25
• Underpressure armature DN 25
• Overflow armature DN 25
• Float valve DN 25
• Expansion vessel 28 l
• Pump for water 95°C 360W, 230V, 50 Hz, Hmax 35

• Probe NTC
• Circuit breaker of regulator 230V 4A
• Motor starter 230V 1,5-4A
• 2 pcs of the electric heating element with input power 6000 W (total 12000 W) – the electric heater serves to heating of water in the tank
• Optionaly : up to 6 pcs of the electric heating element with input power 6000 W = 36kW
• Without the steam heat exchanger

Electric switchboard and other equipment (valid for the NH version : without heating system)

• This version is only passive water boiler
• Without electric switchboard
• Without thermo sensors
• Without water pressure station
• Without thermo regulators
• Without electric heating elements

The Waterworks

The waterworks is always a part of the hot water tank delivery.
A water station is a device that ensures that hot water is available at the required pressure (usually 4 bar) at the outlet of the tank. From the point of view of the powered equipment, the hot water tank therefore appears as a standard water supply connection with a supply of pressurized hot water.
