Whisperline® Water Source Heat Pump | Whalen

Whisperline® Water Source Heat Pump

Whalen’s philosophy is to offer equipment that is flexible enough to meet the design of the building rather than forcing a building to conform to limitations of the equipment. This philosophy is not limited to physical size or optional accessories.

The Whalen Whisperline^® Water Source Heat Pump is a proven concept in air conditioning any type of building – advantageous for new construction and renovation of apartments, condominiums, hotels, senior living facilities, dormitories and office buildings.

The Whisperline^® is capable of performing at entering water temperatures ranging from 20 degrees to 100 degrees F, depending on the configuration you select.

If you’re looking for a unit that offers design flexibility, provides a lower installed cost, reduces maintenance, and incorporates features like aluminum grilles for a superior long-lasting appearance, the Whisperline^® is the natural choice for you.

Whisperline^® Vertical Stack Water Source Heat Pumps from Whalen are an efficient way to provide quiet, comfortable cooling and heating to high rise multi-floor buildings.  These units are economical because they reduce time, material and labor requirements during installation.

Whisperline^® units arrive fully assembled with factory-installed piping packages, controls and risers.  A small footprint allows the units to be furred into columns, walls or closets without the need for expensive horizontal connection piping.

Typical Whisperline^® applications include apartment buildings, condos, office towers, hotels, motels, senior living facilities and dormitories.

Easy to Install and Service

By utilizing a single set of risers, Whisperline^® units are able to stack from floor to floor, thereby simplifying the installation.  For staged installation projects, cabinets can be shipped separately from the refrigerant chassis.

The chassis, which includes the complete refrigerant circuit, slides into the cabinet after the construction debris has been removed to ensure trouble-free operation at start-up.

When a chassis requires service, it can be quickly replaced in a matter of minutes by sliding the existing chassis out and sliding a spare chassis into the cabinet.

Efficient and Environmentally Friendly

With efficiencies up to 15.5 EER, Whisperline^® units are both environmentally and economically friendly.  Operating well above the ASHRAE 90.1 minimum, these units exceed minimum thresholds for most utility rebate and incentive programs.  All units run on Ozone-friendly R-410A refrigerant.

Small in Size … Quiet in Operation

Since we offer one of the smallest footprints in the industry along with customization capabilities including cabinet height, riser locations, handing and discharge arrangements and sizes, your new Whisperline^® units will be installed and operating in significantly less time.

Dual-level vibration isolators are integrated into every unit to help minimize vibration and noise transmission.  An acoustically insulated compressor enclosure further reduces any sound transmission, making these units ideal for noise-sensitive applications.

Supply Opening

Left, Right, Front, Back and Top Combinations – all supply openings are painted black to block the view into the unit.  When one unit is used for two rooms, a sight baffle is placed between the two grilles to maintain privacy.

Supply Grille

Aluminum supply air grilles minimize future maintenance and eliminate oxidation that can be caused from condensation.

Offered in single or double deflection, with or without an opposed blade damper, the Whisperline^® is available with the right grille for your application.

Supply/Return Risers

These are provided to meet the requirements of the job site. Custom lengths can be provided to meet the exact floor-to-floor dimension of the project.

Risers are factory-installed and piped to ball valves within the cabinet, or they can be shipped separately to the job site.

Riser Cover

A galvanized steel protective cover is standard to avoid riser damage during shipping, handling and installation.

Ball Valves

Shutoff valves with hose bib (GHT) connection are standard on every unit.

Fan/Motor Assembly

Plug-in type fan/motor assemblies are easily removed through the return air opening.

Insulation

All units are available with glass fiber high density insulation, with thermal and acoustical properties.

Cabinet

Single-piece galvanized monocoque construction with a snap-lock front panel prevents air leakage through cabinet seams to increase efficiency.

Refrigeration Chassis

The removable chassis is a floating design with insulated compressor compartment and vibration isolation.

Water Hoses

Stainless steel braided hoses connect the chassis to the supply and return water piping, while also isolating the compressor vibration from the building’s piping system.

Inner Service Panel

Removable for access to unit control wiring and internal piping.

Filter

Filters are available in “throwaway” and permanent options.

Drain Pan

Made of 304 Stainless Steel, the Whisperline^® drain pain covers the entire unit bottom to ensure long life and proper management of condensate.

Thermostat

Several thermostat options are available in the following configurations:

• Low voltage
• Plug-in or remote mounted
• Manual or automatic changeover
• Electro-mechanical or electronic.

Acoustical Panel

Standard and flush-mounted acoustical return air panels feature a hinged door to allow for filter removal – without the use of tools.

Unit Tagging

Each Whisperline^® unit from Whalen is individually boxed and tagged with factory and customer-supplied information.  Each unit can be tagged with specific room numbers, riser numbers or any other special requirements of the project.
