INTRODUCTION

• The purpose of this presentation is to assist
  those individuals who may be new to this side of
  the industry and want to feel more comfortable in
  their presentation to the decision maker who is
  purchasing a walk in cooler or freezer.

BASICS - Square footage
Many planners specify a combination of walk-ins
and reach-ins strategically located throughout
the facility to minimize employee movement in
obtaining items The size and type of food
service operation and the frequency and volume of
deliveries will determine how much refrigerated
space is required.

• RULES OF THUMB
•  
• Restaurant refrigeration needs by cubic feet
• Average 3 meals/day 1 1 ½ usable cubic feet per
  person
• Fine Dining 1 meal/day 2 5 usable cubic feet
  per person

BASICS Door locations

• Proper door location and size can have a major
  effect on the overall storage capacity in a
  walk-in cooler or freezer.
• Before locating the door, you need to consider
  the type and size of shelving going to be used
  to maximize the storage capacity.

MAX STORAGE CAPACITY
IMPROPER DOOR LOCATION REDUCES AVAILABLE STORAGE

BASICS Hinging, and Swing clearance

• Door hinging is determined by
• Location of receiving door
• Location of preparation area
• If reach-in refrigerators / freezers are included
  in kitchen
• Use of walk-in
• Basic holding
• Active use

RECEIVINGDOOR
This design shows priority given to receiving
bulk products. Kitchen priority may dictate
reversing the door.

TECHNICAL INFORMATION Size and location of
components
The size and the shape of the cooler and freezer
and the number of door openings combined with the
load of the product is the prime influence of the
size of the refrigeration compressor, condenser
and coil (or unit cooler).

SYSTEMS Top Mounted system
Factory installed Refrigeration systems mounted
to the walk-in ceiling panel pre-charged and
pre-wired ready to start up after final
electrical and plumbing connections are
made. Airflow from each condensing unit is
directed away from the wall

SYSTEMS Indoor Remote System

• Remote site installed refrigeration systems can
  be supplied where required.

• Condensing unit location may be as follows
• Floor or Wall rack
• Within designated mechanical room
• 100 Maximum run is recommended
• Ventilation requirements must be considered

SYSTEMS Outdoor Remote System

• This type of installation is used when adequate
  ventilation is not available. The condensing unit
  is located on the exterior building roof or
  exterior wall.

• 100 Maximum run is recommended
• The Condensing unit is designed for outdoor use

SYSTEMS PTN Penthouse units

• PTN Units are a very reliable and simple
  refrigeration solution in a single package. The
  system comes ready to mount on top of the cooler
  or freezer and requires minimal space. The
  evaporator section is outside of the box allowing
  for maximum use of refrigerated space inside the
  box.

• PROS
• Simple installation
• No piping or loose components
• Indoor models come with a condensate evaporation
  pan eliminating the need for a drain line
• Does not take up any space inside the walk-in
  allowing for more space for storage

Walk-In Walk-in site restrictions

• Careful consideration should be given to any
  obstructions when measuring for a new walk-in
  installation, these can include

• Columns
• Drains
• Plumbing
• Electrical Devices
• Overhead Duct work
• Angled walls

Walk-In Walk-in insulated floors

• Insulated floor panels are available for coolers
  and freezers. Coolers normally do not require
  insulated floors unless they are on a second
  floor. In this case floor panels are required to
  prevent the cold from travelling through the
  building floor and causing condensation to form.
  Freezers always require insulated floor panels.

Walk-In Walk-in insulated floor details

• Curtis provides insulated floor panels when
  required. There are various ways this can be done
  as shown in the following details. The expansion
  joint detail refers to jobs where the General
  contractor insulates the building floor. We do
  not recommend this type of installation because
  we can not guarantee the integrity of the
  expansion joint to our wall panels.

Walk-In Typical Kitchen Cooler / Freezer Layout

• Most commercial kitchens have both a cooler and
  a freezer. The walk-ins are usually the same
  size, however other factors such as menu type,
  frequency of delivery, and type of kitchen i.e.
  fast food, nursing home, banquet facility greatly
  influence individual sizes.

Walk-In Typical Combo Layout

• Whenever there is a walk-in cooler and freezer
  located together as shown they can be
  manufactured using a partition wall. This saves
  space as well as cost. The best layout is to have
  the rooms designed side by side. The advantage of
  this layout is that the freezer door does not
  reduce the interior cooler space. Also, the
  cooler evaporator fan is located at the back of
  the room to ensure optimum air circulation and
  not interfere with the freezer door.

Walk-In Coil Placement

• Whenever possible, the evaporator fan should be
  located at the back of the room blowing towards
  the door. The air direction towards the door will
  help prevent some of the warm air from entering
  the room. This helps maintain proper walk-in
  temperature and humidity levels.

Walk-In Height Clearance
The most common height that is used in the
foodservice industry is 7-11. Increasing the
height can greatly increase the useable space and
aid in air circulation at nominal extra cost.
This additional height can be of great value
where the walk-in footprint size is limited but
vertical space is available.

• Walk-ins are available in the following heights
• 7-11
• 8-5
• 9-0
• 10-0
