Unlike foam-filled units which hide manufacturing defects and make servicing expensive, the sophisticated engineering of our TemperLok  system keeps the spa lightweight, economical to own and operate. The solid cabinet floor construction keeps your spa protected from ground temperatures, moisture, and unwanted pests. It is built from treated wood for longevity, not a brittle plastic, making installation and moving of your unit simple.

PDC Spas has engineered a unique system that maximizes energy efficiency and minimizes heat loss rivaling our foam-filled competitors. The TemperLock system begins with (1) a spa shell foam backing which prevents the spa water heat from escaping. The (2) thick cabinet sidewalls and (3) foamed solid floor base are faced with a reflective thermal blanket, similar to that used by NASA. A (5) foam gasket under the spa lip completes the closed air cavity that traps waste heat from the plumbing and operating pumps. The (6) warmed cabinet air is radiated back to the spa and also passes thru air controls, and the Air’assage system on the LX Series spas, versus cooler outside air. This means efficient operation and energy savings for you. What’s more, the (7) removable side panels provide easy access to the components for inspection.
