ENVISION COMMERCIAL SPECIFICATION CATALOG
High Efficiency
Envision Series is the highest efficiency units available.
Large oversized air coils, water to refrigerant heat ex-
changers and single and dual capacity scroll compressors
provide extremely efficient operation and produce the first
30 EER and 5 COP (ISO 13256-1 GLHP) water-source heat
pump on the market. This efficiency means the Envision
Series requires less loop than any product on the market.
This can mean significant savings on commercial projects.
Quiet Operation
All Envision Series product is ARI 260 sound rated us-
ing third party sound testing. Room Noise Criteria Curves
(NC Curve) may be calculated using data from the ARI
260 ratings giving the engineer total flexibility in assuring
a quiet environment. Please refer to our separate catalog
WaterFurnace Sound Ratings and Performance Catalog
concerning this standard and Envision sound performance
data.
Standard Features
Large low rpm blower with either PSC or optional •
variable speed ECM motors.
Heavy gauge cabinet and 6 vibration isolating hanger •
brackets.
Quiet rotary or scroll compressors in all models •
2-dimension refrigerant piping vibration loops to isolate •
the compressor.
All interior cabinet surfaces including the compressor •
compartment are insulated with 1/2˝ [12.7mm] thick
1-1/2lb [681g] density, surface coated, acoustic type
glass fiber insulation.
Double isolated compressor mounting utilizing eight •
durometer selected rubber grommets and high density
steel.
Super Quiet Option
An optional SuperQuiet Sound Package is also available for
a modest cost features:
Multi-density steel laminate compressor ‘mass’ base •
plate designed to suppress low frequency compressor
noise.
Multi-density laminate lined compressor blanket •
designed to completely surround the compressor on all
six sides and suppress low frequency noise.
Indoor Air Quality (IAQ)
All Envision Series features several IAQ benefits:
Corrosion-free plastic double-sloped drain pan •
eliminates standing water and prevents bacterial growth.
An optional stainless steel drain pan is also available.
Foil-faced fibre insulation in all air handler •
compartments to allow cleanability and inhibit bacteria
growth. Optional non-fibrous closed cell insulation is
also available for more sensitive applications.
Filter rack/Duct collar is field switchable from 1˝ to 2˝ •
[2.54 to 5.1 cm] for more filter options.
Standard supplied filter is a pleated MERV 8, 1˝ [2.54 •
cm]. An optional low static high efficiency 2˝ [5.1 cm]
MERV 13, for LEED certification points, is also available.
Hot Gas Reheat - Dehumidification
With tighter construction and more and more ventilation
air coming into buildings, there is more need now than
ever for dehumidification. Ensuring dehumidification can
provide; consistent employee comfort, a reduction in mold
liability, a reduction in cooling costs. Reduced humidity
also provides an improvement in indoor air quality (IAQ)
thru lower humidity levels which can reduce allergen
levels, inhibit mold and bacterial growth, and provide an
improved computer environment. Reheat can be used
wherever moisture is a problem. In schools, high latent au-
ditoriums and theaters, makeup air units, computer rooms,
and indoor swimming pool rooms are typical applications.
The option consists of a reheat air coil located after the
evaporator air coil and a reclaim valve that diverts the hot
gas into the reheat coil. Neutral air will be provided at typi-
cal WLHP loop temperature.
The reheat option is only available with the FX10 control.
With this control we have three control schemes available:
Room wall dehumidistat – An optional room wall dehumi-
distat that controls the reheat mode thru a 24VAC ‘Hum’
input (On or Off). Setpoint and deadband is determined
by the dehumidistat.
