Description
Chattanooga M-4 Hydrocollator – Part Number 2502
The M-4 Hydrocollator, Chattanooga part number 2502, is a large-capacity mobile heating unit designed for physical therapy clinics, rehabilitation centers, hospitals, chiropractic offices, athletic training facilities, and other professional healthcare environments. Built for demanding clinical use, the unit keeps multiple Chattanooga HotPacs heated and ready for moist-heat therapy throughout the day.
As Chattanooga’s largest mobile Hydrocollator model, the M-4 is an excellent choice for high-volume facilities that regularly treat several patients at the same time. Its durable stainless steel construction, thermostatically controlled operation, large HotPac capacity, and wheeled base make it a dependable addition to busy rehabilitation departments.
Holds Up to 24 Standard HotPacs
The M-4 is designed to hold up to 24 standard-size HotPacs, making it the highest-capacity mobile unit in the Chattanooga Hydrocollator line.
The actual number of packs that fit inside the tank may vary when different sizes are used. Cervical, oversize, knee-shoulder, and specialty HotPacs take up more space than standard packs, so the total capacity will depend on the combination stored inside the unit.
The large internal wire rack helps organize and support the HotPacs while allowing heated water to circulate around them. This helps maintain consistent heating and keeps the packs positioned away from the heating element and temperature-control components near the bottom of the tank.

M-4 Hydrocollator Dimensions
The unit measures approximately:
- Length: 35 inches
- Width: 20 inches
- Height: 33 inches
- Metric dimensions: 89 cm × 51 cm × 84 cm
Durable Stainless Steel Construction
The tank and exterior are made from stainless steel to withstand regular exposure to heated water and repeated daily use. Stainless steel also provides a professional appearance and is easier to clean than many painted or plastic surfaces.
The insulated tank helps retain heat and maintain a consistent water temperature. Routine cleaning and maintenance are still important, particularly in areas with hard water where mineral deposits may develop on the tank, rack, heating element, and other internal components.
The tank should be drained and cleaned according to the manufacturer’s recommendations to help maintain performance and extend the service life of the unit.
Thermostatically Controlled Heating
The M-4 uses a heating element and thermostat to maintain the water within the normal operating temperature range. An overtemperature safety switch provides additional protection if the unit becomes too hot.
When properly filled and operating normally, the Hydrocollator keeps HotPacs ready for professional moist-heat applications. Water temperature should be checked regularly with an accurate thermometer as part of routine clinic safety procedures.
If the unit stops heating, remains only warm, overheats, or cycles inconsistently, it should be removed from service and inspected by a qualified technician.
Mobile Design with Wheels
Although the M-4 is Chattanooga’s largest Hydrocollator, the mobile caster base allows it to be positioned within a clinic or therapy department.
The unit should remain on a level, stable surface during operation. Because it contains a large volume of hot water, it should not be moved while filled unless proper safety precautions are followed.
The wheels make it easier to reposition the unit when it is empty, during cleaning, or when reorganizing a treatment area.

The unit measures approximately:
- Length: 35 inches
- Width: 20 inches
- Height: 33 inches
- Metric dimensions: 89 cm × 51 cm × 84 cm
Because of its size and weight, this unit typically ships by freight rather than standard parcel service. Facilities should confirm that there is adequate space for delivery, placement, and safe access around the unit.
Safe Use and Maintenance
The M-4 contains line-voltage electrical components and a large quantity of heated water. It should only be operated according to the manufacturer’s instructions.
Basic safety and maintenance practices include:
- Keep the tank filled to the proper water level
- Check the water temperature regularly
- Never operate the unit without sufficient water
- Use approved terry covers and insulating layers
- Never place a heated HotPac directly against the skin
- Disconnect the unit before draining or cleaning
- Allow the water and stainless steel surfaces to cool before service
- Inspect the power cord, plug, lid, rack, casters, drain, and controls
- Have internal repairs completed by a qualified technician
Routine inspection can help identify worn parts before they cause downtime or additional damage.
A High-Capacity Moist-Heat Solution
The M-4 Hydrocollator is a dependable choice for large clinics and rehabilitation departments that need a substantial supply of heated HotPacs available throughout the day. Its 24-pack capacity, durable stainless steel tank, mobile base, and temperature-controlled operation make it well suited for demanding professional environments.
For facilities that require more capacity than the SS-2 or M-2 models can provide, Chattanooga part number 2502 offers an efficient and long-lasting moist-heat therapy solution.
