An apparatus includes a manifold heat exchange fitting (32) configured to collect a plurality of fluid streams of fluids having different fluid densities. The fitting includes a body (52) with a generally open fluid collection interior area (56). The body of the heat exchange fitting is positioned in a central fluid path that includes a body inlet (58) and a body outlet (60). A plurality of fluid stream fitting openings (76) in the body are connectable to fluid streams of fluids having different densities delivered from water discharge devices such as an autoclave, a steam sterilizer in the steam cooler. The fluid streams of the fluids having different densities collected in fluid communication in the fluid collection interior area may undergo heat exchange prior to discharge from the body outlet.

A temporary wash basin for a trailer is provided. The temporary wash basin includes a sink portion, a faucet portion, and a pedestal portion. The sink portion includes a basin defining a drain. The faucet portion is connectable to at least one water supply line and controls flow of water into the basin. The pedestal portion suspends the sink portion above a surface at a suitable height to establish sufficient knee clearance to comply with the American with Disabilities Act (ADA). The pedestal portion includes a mounting member to releasably mount the pedestal portion to a portion of the trailer, such as the tongue of the trailer.

Systems, methods, and techniques for cleaning sinks and dishes are provided. In some embodiments, a cleaning system comprises at least one fluid supply, at least one opening in a side wall of a sink basin, and at least one nozzle positioned along an exterior of the sink basin. The nozzle is configured to receive fluid from the fluid supply, and dispense fluid through an opening in a side wall of the sink basin to an interior surface of the sink basin. In some embodiments, the nozzle is configured to dispense fluid to the interior of a sink basin, such that substantially all surfaces of the interior of the sink basin are covered with a thin layer of fluid. In some embodiments, nozzle dispensing angle, duration of a cleaning cycle, flow rate or amount of dispensing fluid, or activation of a cleaning cycle may be manually or automatically controlled.
