General Description:
Hot water storage and fresh water production module with ultra-high efficiency (η=99% @ ΔΤ=1) CALPAK X-FLOW Ultratank. The module has a dual function operation for production of domestic hot water and storage of hot water to support space heating. It has a stainless steel double-coil, counterflow heat exchanger with a pump for direct production of domestic hot water. The unit includes a distinct complete counterflow kit with a circulator and a specific CFA / 3 controller. All X FLOW versions are also available in a 'plus' model which includes an additional heat exchanger for connection with solar collectors. The product holds patented technology with OBI and a 10 year factory warranty.
Advantages:
- Made of high quality steel with robotic welds.
- Built-in stainless steel fast-exchange counterflow heat exchanger with 99% energy efficiency for fresh water supply.
- Maximum operating temperature of 95°C and maximum pressure in the heat exchanger (for domestic hot water) 10bar.
- Ability to connect up to 4 energy sources such as heat pump, boiler, electrical resistance and solar panels.
- Large maintenance port ø508mm.
- Removable polyurethane insulation 100mm.
- Wide range both in the inertia volume (300-2000L) and in the size/performance of the counterflow heat-exchanger (0.8m3 / s – 4.5m3/s @ ΔT =1°C) making the module applicable in a variety of projects including homes, hotels and commercial buildings.
- Great energy savings (~25%) thanks to the top efficiency factor (99%).
- Extremely fast charging compared to conventional containers.
- Protection against the Legionella bacterium thanks to the operation of the stainless steel continuous flow heat exchanger.
- Steady hot water supply with accuracy at the desired temperature.
- Long service life with minimal maintenance costs.
