Chiller & Make up Air Systems

Geoflex Make up Air Systems... As Geoflex manufactures a, Multi-flex modularized “water to water” chilling system that can be used to chill water or to even make ice, if required. The same system can be used to retro-fit and existing make up air system to heat or cool the incoming air according to requirement. With a reversing option on the water to chiller and a ground or in building closed loop, the same system can also heat water. Ice making capabilities for ice rinks or ice storage can be more efficiently developed, if a use for the process heat can be utilized. For example, progressive designers or building owners will make ice for the ice rink and use the normally wasted process heat to heat the change rooms, ice apron, ice melt pit, even the swimming pool next in the same community center and/or other heating opportunities simultaneously. Energy saving potential depends on operating conditions, design variables, space constraints and willingness of the building owner to pay for energy saving features.  As Chilling loads range from 100 percent during the summer to as low as 10 percent in the winter, optimizing the energy-efficient operation of a chiller system requires that the chiller plant be modularized and staged and the plant operation be matched to the chilling load.

Designed to Match any Load…
A Geoflex chiller combined with an air handler offers unparellelled Make-up Air System efficiency and in many cases can also offer a reduced capitol cost. As technology is advancing a a rapid pace with an eye towards much higher efficiencies, Industrial "Water to Water" Chillers are more commonly being used in conjunction with hydronic air handlers to retrofit a make up air system on the roof or in the building. Although Geoflex offers air handlers to match the requirement, in a retro-fit application, it is not uncommon to use the pre-existing air handler by retrofitting hydronic coils within the pre-existing make-up air system to ultimately save the building owner money.

Modularized sizes…
As Geoflex larger capacity “water to water” chillers are modular and are available in multiple tonnages, they can be combined to obtain specific differing high and low capacity requirements, throughout the year. The individual modularized sizes are 10, 12, 15, 17.5, 37.5 ton. If you need to conserve on mechanical floor space, the Geoflex Systems is the best choice as the modularized design allows the units to be stacked or ganged, depending on the mechanical room allocation and configuration. The modular design also accommodates future expansions by allowing modules to be added in stages accommodating increasing cooling requirements.

Simultaneous heating and cooling opportunities…
Geoflex Multi-flex Chillers utilize the scroll compressor technologies.  Since the system uses water on both sides, the opportunities for simultaneous heating and cooling is an obvious advantage over many other systems. The process heat created from the chilling or Ice making process can be used for a myriad of heat rejecting opportunities.

Using your chiller plant as your central heating and cooling system …
In many cases with forward thinking design the same chilling plant can be used to heat and cool the building and offering unparalleled efficiency by incorporating a geothermal loop. Since the system uses water on both sides as the transfer medium, the opportunities for simultaneous heating and cooling are an obvious advantage over many other systems, not to mention using the same system as your hydronic heating and cooling plant for the building.

Size does matter…
The units are designed in such a way as to fit through a standard doorway and can normally be taken up in a standard elevator one at a time, then stacked on site. This will avoid the need for cranes and the need to rip out walls to retro-fit or originally install system.

Load matching…
As Geoflex Chiller Systems are modularized and there are various sizes available, it allows for absolute load matching with the chiller plant. For example, if a 12 where stacked on a 15 ton, the controls can be set up in such a way as to offer two stages, yet 3 capacities for optimal operating efficiencies.

Built in redundancy…
By using the modularized approach, redundancy is essentially built in to the complete system. For example, if you had a 100 ton chiller system, 5 X 20 units, you could easily do maintenance or work on one without affecting the rest of the load. The water lines would be plumbed in a parallel fashion to a header, accomplishing operational isolation. Module isolation, offers true operational redundancy to ensure uninterrupted operation.

Geothermal Linking Opportunity…
If a ground loop is available in the building the same unit can be used as a Geothermal heat pump, as the systems are a designed as extended range units.

Variable temperature profiles…
In some cases varying the output temperatures can be important to the loading characteristics of a given project. With the modularized system, varying temperatures can be easily accommodated with appropriate valving.

Manoeuvrable Advantages
Geoflex “water to water” modules come with fork points to allow for easy manoeuvrability with standard forklifts or pallet jacks.

Reliability Advantages
Proven scroll compressor technology provides reliable, efficient, and quiet operation. On water to water systems, the use of highly efficient stainless steel brazed plate heat exchangers provides maximum performance at both full-load and part-load conditions.

Quick Filter/Strainer Service
Geoflex Chillers come with or without the addition of an optional strainer or filter, which would be located at the back of the system,  allowing for quick and easy service maintenance of such components.
