Description

Newest product range of the highly-efficient heat wheel ventilation units is available in three standard sizes based on the air-flow capacity: 1500, 2500, and 3500 m³/h.

All standard sizes are accomplished with no heater (RV series), with electric heater or water heater option (RH-E or RH-W correspondingly), and ready for operation with all necessary control elements.

MAIN FEATURES

High-efficient EC fans, backward-curved, external rotor. Integrated automatic dampers. Integrated plug-and-play controls. Insulated double-skin frameless casing. ECO-Design’18 compliant. Aluminum rotary heat exchanger. Panel filters G4, F7 (optional). Hinged service doors. Optional outdoor installation with outdoor mounting kit. Web-interface, MODBUS, outputs for optional DX or Hydronic cooling/heating. Complete set of accessories: silencers, VAV, CAV, etc.Operation by RH/CO₂/temperature/constant pressure/timer schedule. Casing:

double skin;
frameless;
40 mm mineral wool 90 kg/m³;
non-flammable;
outer skin: zinc-aluminum;
inner skin: zinc-aluminum;
EN1886 class: D1, T2, TB2;
corrosion resistance according to ISO 12944: class C4.

CONTROLS

Supplied units come with "Plug-&-Play" control system based on Carel programmable controller. Depending on the unit configuration, the system is fitted with 3 temperature sensors: outside, supply, and exhaust air temperature; return water temperature sensor and frost protection relay for water heater configuration; overheating protection relay for electric heater configuration. Standard controller outputs allow to connect various additional sensors. The list of the optional sensors may be found in the accessories section. "Plug-&-Play" control system is fitted with Carel th-Tune control panel which ensures basic setting options and has user friendly interface. Carel pGDe extended control panel may be fitted on request and provides more flexibility and sophisticated control adjustments. The compact dimensions and elegant design make both suitable for all types of premises.

Default control system functions and optional features are listed below (th-Tune):

operation in comfort, precomfort or economy mode;
temperature control;
weekly schedule setting: holiday and special day functions, selection of up to four daily time bands with settings for each operating mode;
coils and heat exchanger auto protection;
air pressure control, airflow and humidity control (with optional sensors);
air quality control (with optional CO₂/IAQ sensors);
freecooling or freeheating mode (according to model);
pumps control, overload alarms and anti-blocking for each pump (according to model);
MODBUS supervisor protocol and user friendly WEB-interface via Ethernet port.

PGDe panel's extended settings:

parameters settings divided by level (user, installer or manufacturer) with password-protected access;
3 adjustable fan speeds;
priority to temperature or humidity control by room/supply/extract sensors;

HEAT WHEEL

Rotary heat exchanger is made of two types of material:

Sensible type (standard).
Enthalpy type. Hygroscopic coating is applied on tape, providing additional latent heat transfer from one stream to another. This feature is especially useful when using a rotor in hot and humid areas in conjunction with air conditioning system.

The advantages are: high efficiency, keeping comfortable humidity and low risk of freezing.

PLUG FANS WITH ELECTRONICALLY COMMUTATED MOTORS (EC MOTORS)

Plug fans with EC motors are used for projects that require high energy efficiency. The advantages of this type of fan are: extremely low power consumption at any speed, no need for external speed control and compact size due to motor with external rotor.

FRAMELESS DESIGN

Frameless casing design excludes thermal bridges, usual for aluminum or steel frame. This significantly increases thermal resistance and reduces heat loss, especially for outdoor installation. It also prevents condensation on the surface when air cooling is on. Casing is made of zinc-aluminum coated sheet steel heat- and sound-insulated with 40 mm mineral wool layer. Benefits of frameless casing:

Better thermal resistance.
Lower weight of the unit.
No thermal bridges.
Suitable for outdoor installation in cold climate.
High mechanical strength.
