LAUNDRY-PAK
Hot Water Supply
Typical Boiler-Tank Arrangement
The Raypak Laundry-Pak is the ideal system for all types of laundries requiring hot water. From the Coin-op
through Commercial applications the Laundry-Pak, when properly sized and applied, will provide the operator with
the necessary hot water at substantial savings in operating cost, maintenance and service.
Exceptional Reliability
The Raypak design utilizes high velocity water flow through the heat exchanger virtually eliminating the formation
of scale and corrosion found in other types of water heaters.
Service and Maintenance Ease
Maintenance and service of the Raypak water heater are made easy through the easy access to controls and heat
exchangers. The water heaters were designed to reduce down time necessary to perform these tasks.
Convenience of Installation
The light weight, low mass and options in indoor or outdoor construction makes the Raypak water heater the most
versatile source of hot water for your laundry needs.
Suitable for replacement, retrofit and new installations, Raypak is the choice.
