        Product Code : CRC MINUS 50
        Brand Name : CRC
        Product Description


        Coolant for electrical and electronic use. CRC Minus 50 is a non-flammable, inert dry coolant spray for maintenance, trouble shooting and repair. Used to cool down parts and components to temperatures below 0°C to a minimum of -50°C; the tracking of intermittent faults, the detection of hairline cracks, and the locating of defective components becomes easier.

        2. FEATURES

        • Protects heat sensitive components from high temperatures during soldering and desoldering.

        • Facilitates precision fitting of metal parts : a short spray will shrink one part so a slip fit becomes possible.

        • Saves maintenance cost and downtime.

        • Non-flammable and inert.

        • No chemical attack of components.

        • Evaporates completely, leaving no residue.

        • Invaluable for testing thermostats and all systems responding to temperature changes.


        • Testing of thermometers and thermostats.

        • Locating defective electrical parts.

        • Finding faulty connectors ...

        • Locating defective diodes , transistors ...

        • Shrink fitting / removal of bushes, bearings, spindles ...

        • Assembly / disassembly of tolerance equipment.

        • Checking of transistor ignition systems.

        • Trimming / machining of rubber bushes ...

        • Removal of chewing gum, adhesives, sweets ... from fabrics, curtains, carpets, chairs, etc (spray until gum is brittle and then break away).

        • Pre-cooling “dental” instruments.

        4. DIRECTIONS

        • Let suspect circuit heat-up, spray one component at a time. Spraying of faulty component will give instantaneous change of output.

        • Hairline cracks in PC will be exposed by frosting up the copper circuitry.

        • Use extension tube for precise aiming and hard to reach areas.

        • A safety data sheet (MSDS) according EU directive 93/112 is available for all CRC products.

        Note :

        with sensitive or stressed plastic parts, the thermal stress induced by strong local cooling must be considered.
