Coolant Transforms and Chills — Just Add Water
Frosty Tech coolant provides perpetual chilling without a power source. Adding water of any quality, including seawater, transforms the powdered cooling agent into a sub-freezing product. It becomes colder than ice in 10–30 seconds, and can maintain this temperature for several hours, even in ambient temperatures up to 95°F (35°C). The coolant powder can be regenerated and reused hundreds of times by allowing the water to evaporate; the regenerated powder retains 100% of its original cooling ability. The product can be adapted to any custom shape or volume, and to flexible or rigid packaging, and can be formulated to achieve almost any freezing point or temperature desired. It is recyclable and does not contain any toxic chemicals.

Drum Dumper Transfers Materials without Creating Dust
The TIP-TITE mobile drum dumper enables dust-free transfer of bulk materials from drums into process equipment and storage vessels. It is mounted on a mobile frame with quick-action floor jacks for stable operation. A hydraulic cylinder raises the drum carriage, sealing the drum rim against a discharge cone, after which a second hydraulic cylinder tips the carriage-hood assembly and drum, stopping at a preset dump angle of 45 deg., 60 deg., or 90 deg. As the assembly approaches its fully tipped position, the outlet of the discharge cone mates with a gasketed receiving-ring inlet fitted to existing process equipment or to the lid of an optional hopper with integral pneumatic, tubular cable, or flexible screw conveyor, creating a dust-tight seal. Once the discharge cone is seated against the gasket, a pneumatically actuated slide-gate valve opens to allow material to enter the receiving vessel.
