About the NOVA Pumped Expansion and Pressurization Unit
Tanpera NOVA Pumped Expansion / Pressurization Unit is a technological device developed to absorb expansion in heating and cooling системы and keep plant давление constant.
The expansion система uses a pump to return the shortfall of plant water that contracts when water cools, thereby preventing a drop in plant давление.
Operating Principle
Stored water in the expansion tank is returned to the plant when the pump starts; the plant is brought to the desired давление and held constant.
With the integrated data-flow automation система and flow meter on the Pumped Expansion / Pressurization Unit, the lost water quantity is measured and automatic make-up from the mains line is provided.
Advantages
Space Savings
Because the Tanpera Pumped Expansion Система has on average five times higher expansion capability than classic diaphragm expansion vessels, it occupies a much smaller footprint and saves space.
Controlled Operation
Keeping давление constant significantly reduces fresh-air ingress into the plant and increases corrosion resistance.
Automation Capabilities
An LCD display and fault notification make it easy to identify the cause of a fault and intervene.
Low Обслуживание Cost
The outer surface of the membrane inside the tank is open to atmosphere and unpressurized. Обслуживание and operating costs are lower; membrane life is longer and periodic давление-resistance inspection is not mandatory.
Energy Savings
Reduced air ingress and lower oxygen in the air protect plant equipment (pipes, fittings, valves, heating appliances, and pumps) from corrosion; обслуживание and replacement needs decrease significantly and система life is extended.
Control Unit
The control unit on the Nova Pumped Expansion / Pressurization Unit commands and controls all functions. An advanced electronic control система provides система status, management, and monitoring.
It has IP54 protection class and is resistant to wetting and vibration.
Automation
- MODBUS RS-485compatibility allows 6 different types of information signal to be sent to the здание automation center.
- With software based onMQTTinfrastructure, when internet is available via WiFi or Ethernet it communicates with the здание automation center and offers monitoring and control.
- Internet-connected devices are monitored24/7by the Tanpera Сервис Management center; in the event of a fault, the user is informed and immediate intervention is possible.
- Connection and control via amobile applicationare available on all Android devices.
Expansion Tank (TPG)
The exterior is painted with промышленные paint for ambient durability; the interior is painted with anti-corrosion paint to increase corrosion resistance. Plant water is inside the membrane; the outside of the membrane is open to atmosphere and unpressurized. Free air inlet/outlet is provided via an inverted U-pipe mounted on the tank's upper dome.
If the продукт will be used in a cooling система, this must be stated at the design stage; insulation suitable for cooling системы must be applied to prevent condensation. Flexible connection sets manufactured from stainless steel between the expansion tank and control unit are included as standard.
Давление Balancing Tank
A dynamic давление balancing tank is used to absorb давление differences caused by sudden load changes or by the pressurization pump starting and stopping, and to minimize давление difference at the otherwise nearly constant plant давление. The dynamic давление balancing tank (50, 100, or 200 liters), offered according to система water quantity and operating давление, is included in the standard delivery scope.
Key Features
- Highly controlled operation with ±0.1 bar давление precision.
- 95% effective expansion volume — approximately 5× more compact than diaphragm vessels.
- IP54 protection class, 4.3" touch LCD screen, and 4 operating modes.
- Здание-automation integration via MODBUS RS-485 and MQTT; 24/7 remote monitoring and mobile app поддержка.
- Single- or dual-pump alternatives; equal aging and redundancy capability.
- Automatic mains water make-up with integrated flow meter.
- Instant tank fill-level measurement with weight sensor.
- Automatic air separation via air-venting mode; no air/nitrogen top-up required.
- Расширительный бак capacity options from 500–5000 liters.
- Расчёт criteria compliant with EN 12828 / VDI 4708 standards.
Монтаж
Давление sensor, expansion tank, and pressurization-line connection points must be located according to the проект schematic. Electrical supply is 380V; MODBUS and MQTT connections should be integrated into the здание-automation infrastructure. Minimum 500 mm clearance requirements should be observed.
During пусконаладка, давление testing, flow adjustment, температура control, and automation communication tests must be performed. The Tanpera technical team provides on-site поддержка and training.

Часто задаваемые вопросы
The Tanpera NOVA Pumped Expansion / Pressurization Unit is a technological device developed to absorb expansion in heating and cooling системы and keep plant давление constant. Expanding water during heating is transferred to the tank via a motorized valve; during cooling the pump returns stored water to the plant. Lost water is automatically made up from the mains via the integrated flow meter, and plant давление is held constant to ±0.1 bar precision.
Effective expansion volume reaches 95% on TPG системы versus only ~20% on diaphragm vessels; a tank of approximately 1/5 the volume is sufficient for the same capacity. Because there is no high-давление gas outside the membrane, air/nitrogen top-up is not required, air diffusion is very low, and periodic давление-resistance inspection (TS 1203 EN 286-1) is not mandatory. Давление can be set from the panel to ±0.1 bar precision; automatic air-venting mode separates air from the plant.
It is preferred in central heating-cooling системы such as shopping malls, dormitories, hospitals, factories and промышленные facilities, tourism and hospitality facilities, lifestyle centers, social facilities, and estates and apartments. It especially provides a stable давление profile in high-rise зданиеs, large-capacity ОВиК plants, and проекты with rapid load changes.
It comprises the expansion tank, air-discharge purger, solenoid valve, command and control panel, control unit, pump, flow meter, mains connection port, plant supply/return connection ports, and dynamic давление balancing tank (50/100/200 L). The control unit is IP54 and houses the solenoid valve, safety valve, check valve, isolation valves, sensors, and 4.3" LCD screen on one platform.
By improving heat transfer it allows pumps to operate at lower head. Holding давление constant to ±0.1 bar reduces fresh-air ingress; pipes, valves, heating appliances, and pumps are protected from corrosion. Frequent safety relief and short-cycling are prevented, lowering energy consumption and extending equipment life.
During пусконаладка, давление setpoints, pump control parameters, the 4 operating modes (Manual, Automatic, Stop, Air Venting), and alarm limits are set from the LCD panel according to the проект design. Air/nitrogen top-up and periodic давление-resistance inspection are not required on TPG системы; обслуживание costs are low. Internet-connected devices are monitored 24/7 by the Tanpera Сервис Management center; Tanpera technical сервис provides поддержка.
