A cooling apparatus includes a base unit in the form of an insulated tank that defines a refrigerant chamber therein for refrigerant, a discharge unit for discharging a flow of air, and a closed circulation system for transferring coolness from the refrigerant in the refrigerant chamber to the air flow in the discharge unit, the circulation system including a first tube coil in the refrigerant chamber, and second tube coil in the discharge unit, a pump, and hoses for conveying coolant from the first tube coil to the second tube coil and back to the pump. The base unit can be harnessed to a user as a backpack and the discharge unit can be a helmet worn by the user, the hoses connected therebetween being flexible. The refrigerant supplied to the refrigerant chamber can be ice and the coolant flowing through the closed circulation system can be water.

A material delivery system comprising: a) a trailer with a deck having two sides and a midportion; b) a molded plastic main tank for holding a liquid material, the main tank having a pair of curved lower side walls below a horizontal midline of the main tank and a first axis generally parallel to the curved lower sides, the main tank being centrally positioned on the midportion of the deck, the main tank anchored to the trailer; c) at least one molded plastic lateral support tank positioned on the deck for providing lateral support to the main tank, the lateral support tank having a concave curved sidewall and a second long axis generally parallel to the curved side, the lateral support tank being positioned adjacent the main tank such that the curved side of the lateral support tank is against the lower side of the main tank below the horizontal midline and the first axis is generally parallel to the second axis; and d) a pump connected to the main tank for delivering the material in the main tank. 7. The material delivery system of claim 6 further comprising an agitation portion comprising a shaft extending into the main tank for agitating material therein, the agitation portion connecting to a drive motor for powering the agitation portion. 8. The material delivery system of claim 7 comprising a second lateral support tank and wherein the lateral support tanks directly engage the curved lower sidewalls of the main tank.
