COMPONENTS OF NOLSEN HEAT CENTER

Combined tank

The Nolsen HWT-500 heat center is a stainless steel combined tank, which is specially developed for heat pump heating / cooling system.

The heat center is equipped with a stainless steel buffer tank with a capacity of 80 liters in the upper section and a 400 liters capacity domestic hot water (DHW) tank with an extra large surface (4.5 m2) ribbed pipe spiral heat exchanger.

The combined tank is surrounded by vapor barrier insulation and we recommend it specially for heating/cooling systems. The upper buffer and the lower domestic hot water tank are separated from each other without thermal bridge.

The storage tank made of stainless steel (DHW SUS316, buffer SUS304) is designed to meet the highest demands, even in industrial systems, but can be also installed in the case of aggressive medium. The size and position of the connectors on the buffer tank are designed to be ideal for heat pump heating/cooling systems.

Magnetic dirt separator

Ensures continuous protection of delicate components against magnetic sludge and all kinds of magnetic dirt in the heating system.

Microbubble separator

The microbubble separator completely separates the gases (air) from the liquid flowing in the heating/cooling system during a special process.

Among its advantages is that even the smallest microbubbles adhere to the PALL rings in the microbubble separator and separate from the liquid.

Thanks to the cone-shaped air chamber, the largest possible distance can be maintained between the liquid level and the vent valve, thus ensuring adequate air separation.

ESBE change-over valves with rotary actuator

Nowadays the ESBE valves, actuators and controllers are adjust the temperature millions of households.

In the Nolsen heat center the switching between the buffer tank and DHW tank is provided by a copper ESBE VRG132 25-10 3-way valve and associated ESBE ARA 230V actuator.

Optional items

Additional installing kits can be purchased separately whiches provide different functions and features in order to provide more personalized and efficient solutions to the users.

Nolsen HomeControl

Custom price

Product properties
The Nolsen HomeControl is specially designed for control, automation and management of Gree heat pumps to achieve the highest comfort and energy efficiency.

The control is provided by a device that has been developed for the heat pump family exclusively matched to the heating center. It covers all the basic functions that may be needed for an automation: it ensures the power supply of the bus, the connection with other connected devices (heating and cooling units, thermostats), and enables remote control from a computer, smartphone or tablet. At least one controller is required per installation. The package contains the software which can be updated via Ethernet connection from the internet.

The module includes all functions, external software is not required, and programming can be done through the web browser, with easy-to-select drop-down menus.

The module allows for very simple installation, only basic electrical knowledge is required for installation and programming.

The device can be mounted on a DIN rail, in an electrical distribution cabinet (standard distribution board).

Functionality
Distributed operation. The core and distinguishing feature of HomeControl is that it’s extremely reliable.

There is no central device: Each device itself is a central device and also an extension at the same time, allowing very high error tolerance. In case of failure, only that functionality is lost what was controlled by the defective device, there is no full function loss.

Self-contain software. The HomeControl IO14 has a built-in software for programming the functionality of the device, control the device and peripheries. The entire software and functionality is accessible from a webbrowser, no need to download and keep an app up-to-date. The firmware can be updated online.

Heating and cooling
Wired up with Modbus thermostats, or 1-Wire temperature sensors, single and cascade heat source control with start & stop signal or Modbus.

Zone control for surface heating and cooling with dew point water temperature regulation, independent, manual, or scheduled room temperature and humidity control for the highest achievable comfort and energy efficiency.
