New Low Carbon Option for Fan Coils and New High Performance Sapphire Fan Coil Range attracts the attention of the industry at the London HEVAR!

 

Quartz's new Low Carbon Option attracted the attention of the industry at the recent HEVAR exhibition. The new Low Carbon option for fan coils is designed from a new perspective and is an exciting development for the industry. Alongside this, the new high performance Sapphire fan coil range was unveiled by the team.

LoCO2 Low Energy Treatment for Fan Coils

Now that the revisions to Part L have taken effect there is an understanding of the direction in which the industry is moving and this, coupled with discussions regarding the future revisions of the regulations, is causing designers to turn more and more to the lowest energy solutions possible for the comfort control of buildings. Initially, this was thought for cooling, to be achievable only with a chilled beam or ceiling approach but now the more enlightened engineers are discovering that all may not be as rosy as it first appeared with such products. Oversupply of fresh air and inflexibility in layout following installation are just two of the issues to be considered. The opportunity therefore existed for a fan coil approach with energy use approaching the chilled beam and with similar or better whole life costs. Quartz have therefore developed an energy saving option, LoCO2, for their standard fan coil ranges that offer such features.

The main areas for energy saving are in the use of higher temperature water for cooling (enables free cooling and high chiller efficiency), lower water temperature for heating (enables the use of condensing boilers or heat pumps) and reduction in the use of energy for air movement. The LoCO2 option enables all of these areas to be addressed.

LoCO2 has a separate coil for heating designed to maintain typical heating duties whilst utilising low temperature water (typically 50/30°C) and a specialist cooling coil that will maintain cooling duties when operating with (relatively) high temperature cooling water (12/16°C). In addition, the fan coils are fitted with ec\dc motors that should be operated with the Quartz suggested strategy that modulates the fan speed with respect to occupancy thereby reducing energy use.

When compared to the active beam approach, LoCO2 has a much lower capital cost and the small running and maintenance costs can be offset against the fan power required for the increased fresh air supply for the active chilled beam. The overall whole life cost will therefore be similar or possibly better for LoCO2 in addition to retaining all of the flexibility in application and operation for which fan coils are renowned.

LoCO2 can be applied to both the Sapphire and Amber ranges of fan coil. The concept was launched at the London HEVAR exhibition (24th – 25th September).

 

New High Performance Sapphire Fan Coil Range

As a leading manufacturer of chilled water products, Quartz are continually reviewing their product ranges and have thus totally revised their tried and tested Sapphire range to incorporate the latest innovations in the market place to create the new Sapphire range.

Previously, the Sapphire fan coils were 275mm deep making them popular with designers as they enable the direct connection of 250mm diameter ductwork with no tricky transition pieces or dropped plenums. As one of the older models in the Quartz range, however, the objective of the design team was to maintain all of the tried and tested features of the Sapphire whilst enhancing the product with features and improving competitiveness. This exercise was required not only for the UK market but also for Quartz’s substantial export markets.

The result of the re-design is the new Sapphire range which now has an identical footprint to the more modern Amber range and incorporates the features of; mitred plenums (to assist in ductwork connection), free flow drain tray (to guarantee condensate drainage) and pleated filter (reducing maintenance requirement). In addition, the commonality of components will assist in improving both competitiveness and production lead times.

The new LoCO2 energy saving option also being released by Quartz can be applied to the new Sapphire range.

The official launch for the new range is the London HEVAR exhibition (24th – 25th September) and information on the new product will be available on the Quartz Stand No. 47.
