While many companies make the claim that they are built for the replacement market, what they offer is the same generic, canned approach for every situation. Of course almost every application is different in some respect, from humidity and pressurization challenges, to space constraints. Add in punitive utility rate structures, and a future where closed power plants mean ever-higher energy costs. The one thing that all retrofit projects do have in common is that there are always new challenges from what was anticipated at the start of the job. Successful retrofit/replacement projects demand flexibility and and an attention to detail that comes from years of application experience.
Using a FANWALL® system to replace older, end of life fans in existing air handlers can be the most cost-effective solution for avoiding the cost and business disruption of an air handler failure. Energy savings can be 40% or more. In many cases, equipment access is a barrier to a fan or air handler replacement because it cannot be accomplished without the time and expense of a major tear-out and reconstruction project. A FANWALL system can minimize this and other barriers.
- The modular design of FANWALL system allows individual cubes to be navigated through a standard 3-foot door and assembled inside the existing air handler cabinet.
- There is no need to have a crane on site as is often the case with larger, more conventional fans.
- The performance of the new system can be upgraded to better match actual capacity and airflow requirements.
- Ancillary components such as sound attenuators and air blenders that created static pressure penalties in the old system can be removed.
- Retrofits often can occur over a weekend or during unoccupied time frames to minimize downtime or disruption of normal business.
When space is tight and downtime is unacceptable, modular chillers are available in multiple tonnages that can be combined to obtain specific project turndown and capacity requirements. The modular design also accommodates future expansions by allowing modules to be added in stages accommodating increasing cooling requirements. The modular chiller’s compact design allows for easy access to existing equipment rooms minimizing installation cost for replacement or new installation. Compact footprints and easily maneuverable designs allow modules to fit through 36” doorways, around tight corners and into standard elevators. Chiller modules include base cutouts and are easily transported with standard forklifts or pallet jacks.
What would your customer do if you freed up a few hundred kW for them to use on new clients or production capacity? Using an Evaporative Condensing system to replace an old air-cooled machine can result in an immediate 30% savings in electrical consumption costs, and up to 40% savings in demand charges. And since Evaporative Condensing often has a much smaller footprint than air-cooled on a ton-for-ton basis, finding space for this improvent isn’t a problem. Due to the flexibility you have in equipment design, Evaporative Condensing chillers can also greatly reduce the total retrofit costs.
- Chillers can be provided with complete pumping systems, allowing for a hot-swap for mission critical applications
- Desuperheaters and free-cooling economizers eliminate the need for a separate, dedicated dry cooler
- Factory installed glycol and water-treatment systems
- Performance of the system can be upgraded to better match actual capacity and waterflow requirements
- Variable-primary pumping controls allow for the replacement of energy-wasting three-way valves
