The Whalen Company’s large capacity belt-drive horizontal and vertical fan coil units combine cooling, heating, humidity control and filtration with the simplicity of a single, compact fan coil unit with an expanded operating range for additional applications.
Design features:
- Designed to Deliver Strong Value
- Year-round comfort and reliability
- Lower installation and operating cost
- Clean and quiet operation
Features and Benefits:
- Most buildings run at peak capacity only a few weeks during the year. The Innoline® 50/50 unit takes advantage of this fact by using smaller pumps that can be staged to reduce energy consumption compared to operating a single larger pump.
- Combine this with the operation of only one of the two fans during part of the year, and the energy savings are significant.
- The Innoline® 50/50 unit is practically maintenance-free, with only the filter requiring periodic replacement or cleaning. There are also no control valves and piping joints that can lead to leaks and service calls.
- The overall system main size is reduced by 50 percent since each side of an Innoline® 50/50 unit handles one-half of total cooling requirements. This translates into smaller standard pumps and reduced labor times.
- By design, each unit is naturally balanced once the flow is established in the riser. The balancing and venting of individual units is a “task of the past.” Instead, you gain the benefits of a reverse return balancing system without the need to run an express riser within the building.
- By designing the Innoline® 50/50 unit with two equally sized heat ex- changers, 50% system redundancy is provided during peak the heating and cooling seasons.
- Valve Control VS. Fan Cycle Control – Condensation and/or moisture are formed on the fins of any fan coil unit when high humidity (dew point) levels are allowed to exist in the surround- ing space. The riser heat-exchanger system continuously dehumidifies the room air by allowing the chilled water coil to be active at all times. Units incorporating control valves to shut off the chilled water supply allow residual moisture formed during the dehumidifying process to re-evaporate into the air stream. The phenomenon is expedited when the fan is allowed to run continuously.
- The dual fan arrangement of the Innoline® 50/50 unit provides superior dehumidifying at low load conditions typically found during intermediate seasons. By having a fan/coil combination more closely matched to the lower room load, the unit runs longer to remove moisture from the air. At these conditions, a unit with a single fan and water coil will cool the room too quickly to achieve adequate moisture removal.
- Most households and businesses select fan cycling control when offered the option of both systems. If a continuous running fan is preferred, then power consumption is not the primary concern. Both systems are available.
- The Whalen return air opening with an architectural aluminum grille is sized for easy removal of the fan motor and blower assembly.
- Return air grilles are hinged aluminum that allow for changing the filter without the use of tools.
- All supply openings are painted black to block view into the unit. When one unit is used for two rooms, a sight baffle is used between the two grilles.
Building Owners:
- Energy savings and reduced operating costs are achieved as each side of the unit can operate independently, reducing pumping and fan horse power usage
- Two fans per unit sized for 50 percent of total CFM required reduce operating costs
- Simplified maintenance procedures
- Elimination of all electric valves and flow control valves
- Absence of brazed joints within the cabinet
- Low maintenance, permanently lubricated, no valves, requires filter change only
- Quiet operation
- 4-pipe control during intermediate seasons
- Design aesthetics, with aluminum grilles instead of unsightly steel panels and access openings
Contractor s:
- No unit balancing or reverse return piping
- No venting of individual units
- Supply/return main costs are reduced due to 50% performance capability
- Reduced number of solder joints
- Small riser/drain grouping (10 in. core drill)
- Galvanized cabinet is ideal for direct drywall application – no framing required
- Uniform riser pipe sizing simplifies distribution of units in a building
- Units can be installed early in the construction cycle
- Significant reduction in total installation and operating costs
