DESCRIPTION
STANDARD FEATURES
The Reznor Model PCD Series units are indirect-red/makeup air system designed for either indoor or outdoor
installation. Units can be congured for either vertical, horizontal for oor mount, outdoor pad mount, rooftop or
suspended installation. Select from top, bottom or horizontal discharge supply air options. Model PCD systems
are available to operate on either natural gas, propane or fuel oil. This catalog details features and specications for heating capacities ranging from 200 to 6,000 MBH output. Larger sizes are available on special order
basis (contact your Reznor Representative for more more information) High cfm versions (Model HPCD) are
also available.
The basic cabinet is constructed of 18 gauge galvaneal with a grey enamel nish. Other nishes are available.
The standard cabinet is a single wall with 1” thick, 1.5 lb. neoprene coated insulation. High density (2 lb.) insulation or 2” thick insulation can be selected. A 22 gauge interior liner is standard on the burner section. Optional
solid (for cleaning) or perforated (for sound attenuation) liners are available on other sections.
Vertical units (Model PCDV) can be shipped with a 3’ or 5’ mounting stand for eld attachment. The mounting
stand can be screened, or it can be insulated with one or two anged inlets with or without dampers. A louvered
inlet plenum can be shipped separately with outdoor vertical or horizontal units.
Discharge air openings can be shipped with two position motorized discharge dampers - low leak dampers also
available. Other air distribution options include trapezoidal cowls with horizontal louvers; 4-sided (360 degrees)
louvered discharge plenum; or 90 degree discharge cowls.
A 409 stainless steel primary and secondary heat exchanger is standard on Model PCD. Optional 304 stainless
steel can be substituted for both heat exchangers or only the primary heat exchanger. Model PCD high can be
ordered with a standard gravity vent or induced draft vent.
Units can be arranged for 100% outside or return air, or a mixing box can be specied with 3-position motorized dampers. Other modules can be included with Model PCD and shipped separately for eld attachment
including an inlet louvered hood, evaporative cooling section, lter cabinet, service platform and/or cooling coil
cabinet.
Model PCD and HPCD meet ETL (ANSI) Standards for installation in the United States and CGA (CSA) Standards for installation in Canada.
All units are factory wired, piped and test red.

SIZE SELECTION
How to determine the size of Model
PCD
Example 1: Make-Up Air
Model PCD are designated by their MBH output. Thus a PCD75 has 750 MBH output, or 750,000 BTUH.
● All PCD units are 80% efcient at high re, thus, output is BTUH input x 0.80
● Once you have chosen your required BTUH output, you can use BTUH output ÷ 0.80 to nd your required
input, or actual gas consumption. Using the desired output you can select your model.
● Choose your airow (this may be your rst step if the unit is applied in a make-up air situation)
● Calculate your TSP (add your ESP with your accessories – accessory pressure drops can be found after the
unit ESP table). With your airow and TSP selected you can nd your BHP from the performance table.
● Given the entering and leaving air dry bulb temperatures or temperature rise, the equation below can be
used to calculate the required MBH capacity
▬ MBH Capacity = (CFM x C x (LAT-EAT)) ÷ 0.80 ÷ 1000
▬ MBH capacity: BTUH/1000 (British Thermal Units per hour)
▬ CFM: Cubic Feet per Minute of air
▬ C: Gas constant of 1.08 based on air density at 75°F
▬ EAT: Entering air dry bulb temperature (°F)
▬ LAT: Leaving air dry bulb temperature (°F)
▬ 0.8: (80%) Series Efciency
A manufacturing facility needs pressurization via makeup air. A pressurization of 10% is deemed to be appropriate, and it is determined that 25,720 CFM exhaust is required. The design ambient is -20°F, and desired
discharge temperature is 70°F. Units will be roof mounted, down discharge, and will have an ESP of 0.60” w.c.
Select the appropriate size, and nd the BHP for the unit.
Selection:
● Since we are exhausting 25,720 CFM, and desire 10% pressurization, we can calculate that we need 28,300
CFM of supply air (25,720 x 110% = 28,300)
● We know our EAT = -20°F, and LAT = 70°F, thus we can calculate:
▬ MBH Output Capacity = (CFM x C x (LAT-EAT)) ÷ 1000
▬ MBH Output Capacity = (28,300 x 1.08 x (70 - (-20))) ÷ 1000
▬ MBH Output Capacity = 2,750.76
● The closest size available is the Model PCDH275 which has 2,750 MBH output, and 3,437.5 MBH input
We can now calculate our TSP:
● We are selecting the basic options – inlet lters and damper
● Inlet damper = 0.1” w.c.
● Inlet Filters = 0.3” w.c.
▬ TSP = ESP + Accessories
▬ TSP = 0.60 + 0.1 + 0.3
▬ TSP = 1.0” W.C.
● Consulting the chart for the PCD275 at 28,300 CFM and 1.0” W.C we nd our BHP = 16.28 BHP – Thus we
need a 20.0 HP motor minimum.

CONFIGURATION SELECTION (cont’d)
Example 2: Heat-Vent Unit
Selection:
Example 3: Heating Only Unit
A small warehouse needs a minimum of 20% fresh air in unoccupied (night time) mode and 100% fresh air in
occupied mode (during the day with forklift in the building). It has been calculated that at -30°F the room loses
1,000,000 BTUH. It has been determined that 11,000 CFM is required for the application. The outdoor air is
-30°F, and desired leaving air is 75°F. Return air will be 70°F. ESP is calculated to be 0.5” w.c. Select the appropriate model and nd the BHP for the unit.
Part 1 (Unoccupied mode)
● We only bring in 20% outside air in this mode, thus 2,200 CFM is outside air and 8,800 CFM is return air
● We know our EAT for outside air = -30°F, and LAT = 75°F, thus we can calculate:
▬ MBH Capacity = (CFM x C x (LAT - EAT)) ÷ 1000
▬ MBH Capacity = (2,200 x 1.08 x (75 - (-30))) ÷ 1000
▬ MBH Capacity = 249.48
● We also know that the room is losing 1,000 MBH, thus we need to add that to the calculation. Thus the total
Heat input capacity required = 1,250 MBH
● Before we select our model we must check the occupied mode to ensure we have sufcient heat capacity.
Part 2 (Occupied mode)
● We will be delivering 11,000 CFM of outside in this mode
● We know our EAT for outside air = -30°F, and LAT = 75°F, thus we can calculate:
▬ MBH Capacity = (CFM x C x (LAT - EAT)) ÷ 0.80 ÷ 1000
▬ MBH Capacity = (11,000 x 1.08 x (75 - (-30))) ÷ 0.80 ÷ 1000
▬ MBH Capacity = 1,247.40
● Thus to satisfy both options we need to use a PCDH125.
Note: In this example we are assuming there is an alternate source of heat that will be used during occupied
mode to make-up for the heat loss of the warehouse, which will not be used in unoccupied mode.
We can now calculate our TSP:
● We are selecting the basic options – inlet lters and damper
● Inlet damper = 0.1” w.c.
● Inlet Filters = 0.3” w.c.
▬ TSP = ESP + Accessories
▬ TSP = 0.50 + 0.1 + 0.3
▬ TSP = 0.9” W.C. (Round up to 1.0” w.c.)
● Consulting the chart for the PCDH125 at 11,000 CFM (use 11,574 CFM) and 1.0” w.c., we nd our BHP =
5.75 BHP – We can use a 7.5 hp motor.
A door heater for a large overhead door can potentially see 100% fresh air during times when the overhead
doors open frequently. Thus a durable Model PCD unit should be selected for this application. The appropriate
amount of air is determined to be 18,000 CFM at 0.5” w.c. for the vestibule, and 1,250 MBH is calculated to be
the appropriate amount of heat capacity required. Select the appropriate model and nd the BHP for the unit.
Selection:
● Since the heating load calculation has already been completed we simply need to use the heating capacity
and match it up with the appropriate Model PCD
● PCD125 is the appropriate model for 1,250 MBH
We can now calculate our TSP:
● We are selecting the basic options – inlet lters and damper
● Inlet damper = 0.1” w.c.
● Inlet Filters 0.3” w.c.
▬ TSP = ESP + Accessories
▬ TSP = 0.50 + 0.1 + 0.3
▬ TSP = 0.9” w.c. (Round up to 1.0” W.C)
● Consulting the chart for the PCD125 at 18,000 CFM (this value falls between 16,534 CFM and 19,290 CFM)
and 1.0” W.C we nd our BHP is between 9.59 BHP and 13.12 BHP. A 15 HP motor should be used.
