Consistent Moist-Heat Therapy

The Hydrocollator SS-2 heats and stores Chattanooga HotPacs in thermostatically controlled water. The unit maintains an operating temperature of approximately 160°F to 165°F, helping clinics keep HotPacs ready for treatment throughout the day.

Moist heat is commonly used by healthcare professionals before stretching, therapeutic exercise, massage, manual therapy, and other rehabilitation treatments. The heated pack must always be placed inside an appropriate terry cover with sufficient insulating layers before being applied to a patient.

Treatment temperature, duration, and application should be determined by a qualified healthcare provider.

Durable Stainless-Steel Construction

The tank and exterior are constructed from stainless steel for durability in professional healthcare environments. Stainless steel is well suited for repeated exposure to warm water and routine cleaning.

The SS-2 also includes fiberglass insulation, which helps reduce heat loss and improve energy efficiency. Its removable internal rack organizes the HotPacs and keeps them positioned away from the heating components at the bottom of the tank.

Routine cleaning remains important. Mineral deposits and sediment can accumulate inside the unit, particularly in facilities with hard water. The tank and rack should be cleaned according to the manufacturer’s instructions.

Mobile Design with Swivel Casters

The Hydrocollator SS-2 is mounted on 3-inch swivel rubber casters, allowing it to be moved between treatment areas when empty or when proper safety procedures are followed.

The rubber casters are designed to provide quiet, smooth movement across clinic flooring. During normal operation, the unit should remain on a level and stable surface.

Because the tank contains hot water, the unit should not be moved while filled unless the manufacturer’s instructions permit it and staff follow appropriate safety procedures.

Easy to Fill, Drain, and Maintain

The Hydrocollator SS-2 does not require permanent plumbing. The unit can be filled manually and connected to a standard compatible electrical outlet.

A drain valve allows the water to be removed during cleaning and maintenance. Before draining or servicing the unit, it should be disconnected from electrical power and allowed to cool.

The simple design makes it easier for clinics to perform routine maintenance, including:

Draining and replacing the water
Cleaning the stainless-steel tank
Removing mineral buildup
Inspecting the internal rack
Checking the power cord and controls
Examining the casters and drain valve
Monitoring the water temperature
