VOLCANO and WING equipped with EC motors as a standard - energy efficient air water heater and air curtain by VTS creates trend for HVAC branch.



The motors used in the industry have a significant share in the global consumption of electric power. These values are so great that not only the motor users that cover the cost of power, but also parliaments in many countries are interested in their reduction. The European Union has been publishing appropriate regulations, imposing an obligation of using increasingly more efficient drives on manufacturers of electrical devices.

We strongly believe that again VTS, instead of following others, is creating new green trend in the market offering our clients not just a products. We provide units that saves money, are quite and smoothly regulated.
 

Proven devices now come with a new heart

The heart of every air handling unit is a fan assembly, i.e. a fan rotor driven by a motor. It decides about the main parameters of device operation. VTS engineers, while drawing on their long-term production and exploitation experience optimised in aerodynamic terms the form of the axial rotor Volcano and the radial rotor in Wing, which ensured the maximisation of efficiency. The energy cost-effectiveness, obtained on the fan, has been combined with power saving, resulting from the use of high-performance EC motors.

 

What is EC motors characteristics indeed?

It is brushless, direct current, Electronically Commutated motor, having the coils in the stator and permanent magnets in its rotor. Thanks to elimination of brushes – a part subjected to fast wear – EC motors are recognized as the most durable and reliable drives ever created. Elimination of brushes makes, that now, bearings remain the only parts considered as potentially subjected to wearing process in the whole EC motor.

EC motors are electronically commutated brushless direct current motors. They are characterised by:

  • Less energy consumption in comparison to AC drives
  • Higher efficiency in wide range of performance
  • Higher durability
  • Less maintenance cost
  • Silent operation at high revolutions
  • Smooth regulation by means of 0-10 volts signal of MODUBS RTU protocol
  • Smaller physical dimensions at the same capacity

What are the user advantages from the use of EC motors in a heater or in an air curtain?

High efficiency of EC motors directly impacts the reduction of exploitation costs, which offers real savings to the customers. Additionally, the possibility of connecting 8 devices to one VOLCANO EC or WING EC controller also reduces investment costs. We have prepared a number of financial simulations; an example of one of them can be seen in another article. In general, EC motors can reduce the exploitation costs by 40% in comparison with the previous generation motors.

Non-financial factors which support the selection of devices with an EC motor are primarily the comfort of silent operation of devices- smooth control of rotational speed enables the adaptation of the device to particular needs. Additionally, the customer can have a peace of mind- VTS devices are covered by a 5-year guarantee, and the devices are made with care for the natural environment.


Dedicated control

Exercising of all the advantages of the Volcano and Wing solutions would not be possible without an appropriate control system. VTS offers microprocessor controllers, which are adapted, among others, to the adjustment of rotational speed or the programming of operating schedule. The controllers (table 1) perfectly comply with the most recent trends as well as the highest technical and aesthetic standards.


 

 

  • Co-operation with external temperature sensors

  • A calendar of heater operation time for working and weekend days.

  • Operation in BMS systems

  • The possibility of automatic and 3-degree adjustment of the rotational speed

  • The possibility of connecting even 8 heaters to one controller!

  • Support of a door opening sensor

  • A calendar of curtain operation time for working and weekend days.

  • Operation in BMS systems

  • The 3-degree adjustment of the rotational speed and 2-degree adjustment of the heating power

  • The possibility of connecting even 8 curtains to one controller!

Table 1. The picture and the description of VOLCANO EC and WING EC

 
The Volcano EC and Wing EC controller in itself can control 1 heater or air curtain, but its great advantage is the possibility of controlling a group of up to 8 devices. Moreover, each controller can monitor and manage the operation of devices from the external level of BMS.
 

Connection with BMS

BMS is a Building Managment System, whose task consists in the integration of all automation systems of devices installed in the building. The most important task of the system from the user perspective is the reduction of building exploitation costs related to electric power, ventilation, heating or cooling systems while ensuring adequate comfort. In response to the growing requirements, VTS has equipped its devices in the possibility of connection with the Building Management Systems (BMS). It is possible to provide a direct connection with EC motors without the use of automation or via automation, according to the customer’s selection. Both versions use the MODBUS RTU protocol, RS485 bus for the communication with BMS.

 

VTS marks an ecological trend in the HVAC branch.



VTS, being aware of growing customers’ expectations, changing market trends and legal conditions has marked a new trend in the branch- ecological and economic solutions cannot be an addition to the offer, but they must become a standard and the only right solution.

VOLCANO and WING devices created by VTS thanks to their innovativeness, high quality of applied materials as well as ultramodern style make this company not only an unquestionable leader on European and eastern markets, but primarily the creator of new, economically justified trends in the whole branch.
