Such trucks are equipped with a further wide variety of equipment, accessories, and systems to prevent or minimize liquid carryover into the vacuum pump during loading or off-loading. These include filters, baffles, deflectors, swash plates, moisture traps or scrubbers, cyclones, screens, baskets, bags and cartridges, internal and secondary shut-offs, multiple routings, scrubber drain valves, isolation valves, bleeder valves, manifold/inlet/outlet valves and external scrubbers. Such trucks are often protected from over-pressure by relief valves or rupture discs such as pop-offs.
The same problems occur with stationary tanks.
A need exists to prevent vehicular water tank valves, scrubber tanks and lines from freezing, and to undue such freezing when it occurs.
General Summary
The present invention teaches the use of vehicle engine coolant circulated through couplings, sleeves or similar fittings which are utilized at the locations where freezing is likely to occur.
In one embodiment, the invention teaches a manifold heater built to mate with pipe flanges holding between them an ordinary valve.
In an alternative embodiment, the invention teaches a scrubber heater meant to serve as a short section of vacuum line/drain line positioned just beneath the scrubber so as to warm the air entering the scrubber and the scrubber itself as well.
In an alternative embodiment, the invention teaches a quick disconnect cuff for unfreezing valves, pipes or accessories other than those on the vehicle or stationary tank equipped with the invention.
