Floor Standing Unit

Design Features

Double Skin Access Panel With Gasket Lining

The solid and rigid double skin insulated access panels on the G-VOLUTION Series ensure excellent sound isolation and greatly reduce the breakout noise of the unit. The special FERMAPOR gasket on the door panels effectively eliminates air leakage from the units. This gasket is applied to the door panels using a special machine to ensure strong bonding between the gasket and the panels, thus increasing the reliability of the whole panel assembly.

Electrical and Control Panel

High and low voltage cables are segregated and each component is protected by individual MCB. AC3 components such as fan motors and compressors are protected by manual motor starters. All cabling are colour coded and numbered for easy reference.

Electronic Expansion Valve (EEV)

The innovative Electronic Expansion Valve (EEV) provides highly efficient control of refrigerant flow based on real-time feedback. The EEV can provide fast, stable and precise control even under low-load condition. The presence of the temperature and pressure probe allow real time monitoring of suction temperature and pressure as well as the superheat of the system.

Coil

Large coil face area allows more cooling capacity at lower face velocity. Therefore, the unit can achieve better efficiency while at the same time minimizing the air side pressure loss. Hydrophilic fin provides additional protection to the coil and at the same time, ensures fast removal of condensate on the coil.

Scroll Compressor

High efficiency hermetic scroll compressors provide reliability, quiet and superior cooling performance. For even better part load efficiency, and control precision, some models can be fitted with scroll compressor with DC Inverter technology. DC Inverter scroll compressor enables capacity regulation with variable speed. Thus can perfectly matching the heat load without start/stop cycling. All compressors are with screw thread connection for easy service and maintenance.

3 Types of Fan Configuration

The G-VOLUTION Direct Expansion System offers 3 types of fan configuration. DIDW centrifugal fan driven by AC motor as standard while high efficiency Electronically Commutated (EC) fan is offered as option. Apart from increasing the efficiency of the units, EC fan also enables various control strategies for data center cooling such as under floor pressure control and variable airflow control. For downflow system. if the raise floor has sufficient height (>400mm), then the efficiency of the unit can be further improved as much as 15% by locating the EC fan under the raise floor. For models using DC Inverter Compressor, only EC fans (both in-unit and underfloor) are available to complement the capacity regulation capability of the units.

G-Volution Series

ES Range

ES Range offers a direct expansion system which can also be fitted with DC Inverter Compressors. It will be able to regulate the capacity based on actual cooling demand from 30% to 100%. It can control the supply of air temperature precisely within a tight operating tolerance resulting in a reduction of the unit energy consumption with higher efficiency during part load operation.

ECL Range

Chilled Water series comes with exclusively two different range; EC and ECL to suit various requirements and applications.

The EC range is designed to fit in large coils with a maximum heat exchange surface. It has a low coil face velocity thus reducing air friction loss, therefore ensuring the units operate at the highest efficiency.

The ECL range comes standard with an underfloor EC fan as standard and is designed to deliver maximum performance with minimum footprint. Cooling coils are designed and arranged to achieve maximum heat transfer surface area within limited cabinet space. ECL range is best suited for data centers with elevated floorings.

Electronic Pressure Independent Valve (EPIV) can be fitted into the EC & ECL range as options that will incorporate a flow meter and a 2-way control valve. The actuator has a powerful algorithm that modulates the control valve to maintain and measure the water flow rate regardless of variations in system differential pressure.

EH Range

Unique dual coil series, the EH range is designed to provide the highest level of redundancy. There are two types of dual coil system; dual chilled water system or a combination of direct expansion and chilled water system. The EH range complies with various applications preventing downtime whilst safeguarding the operations of your data center. Should a fault be detected in the primary system, the unit operating condition will be closely monitored while performing the switch from primary to the secondary system with CITEC powerful Genius 5+ controller.

CITEC EH Range ‘C Version’ is designed with two sets of chilled water coil within a single cabinet, connected to two independent; primary and secondary sources. During maintenance for the primary source or should a fault be detected, the unit shall changeover to the secondary source for continuous operation.

CITEC EH Range ‘A/W’ version consists of a dual system; the DX system and the CW system within a single cabinet. Systems will operate utilising low cost chilled water as a primary source. The DX system will take-over should a fault with the chilled water be detected or during chiller shut down for maintenance. In buildings with centralized chilled water supply during office hours, chilled water can be utilized as a primary source and switched to the DX system as a secondary source after office hours.

Innovative Modular Design Complies With Technology

An underfloor version of the EC fan is available for downflow models. Studies have shown that the placement of underfloor EC fans contribute to a 10% to 15% improvement in performance and is recommended for users who would like to utilize the full capacity of the EC fan. These fans are pre-wired and pre-packaged into the Precision Air Conditioning unit prior to delivery for instant installation.

With the innovation of CITEC, underfloor EC fan is mounted to the base of unit and lowered down to under-raised floor during site installation, promoting:

• Better air flow distribution
• Reduction of fan power inputs
• Convenience of service and maintenance
• Cost saving on installation and equipment
