NULITE pressurized water tanks store and prepare hot water in systems served by heat pumps, solar collectors, and other hydronic heat sources. The brochure lists standard capacities from 80 to 2000 L and allows project-specific customization.
Capacity and dimensional range
Published sizes include 80, 100, 150, 200, 250, 300, 400, 500, 600, 800, 1000, 1500, and 2000 L. Overall diameter ranges from 470 to 1200 mm and height from 800 to 2400 mm. Inner-tank thickness increases from 1.0 to 2.0 mm and outer-casing thickness from 0.5 to 0.6 mm. A 50 mm foamed insulation layer is shown between the inner vessel and outer casing.
Construction and customization
The manufacturer's drawing shows a vertical cylindrical vessel with internal heat-exchanger coils and multiple hydraulic connection levels. Galvanized sheet metal, SUS 201, SUS 304, and SUS 316 are listed as material options for the inner tank and outer casing. The brochure states that coil length, nozzle size, tank dimensions, an additional electric heater, and a magnesium anode can be customized.
System integration
The brochure illustrates a storage tank operating with an air-source heat pump, solar collectors, a domestic hot-water circuit, and a separate heating buffer tank. This arrangement can separate sanitary hot-water production from low-temperature heating or cooling circuits.
Applications
- houses and apartments;
- hotels, dormitories, and sports facilities;
- healthcare, educational, and wellness buildings;
- restaurants, kitchens, and service businesses;
- heat-pump or solar domestic hot-water systems;
- hybrid systems using multiple heat sources.
Information required before ordering
Selection must consider daily and peak hot-water demand, target temperature, heat-source output, coil area, number of circuits, inner-tank material, available plant-room dimensions, and nozzle positions. The supplied brochure does not state the maximum working pressure, temperature limit, or sanitary approvals for a specific configuration; these parameters must be confirmed in writing before ordering.
