Abstract: This invention relates to a spray head for delivering a fluid having a plurality of passages connecting a plurality of inlets to a plurality of outlets whereby the passages are disposed at selected angles to produce different fluid flow distances from the outlet to define a selected pattern. The selected pattern defines geometric patterns such as a square, rectangle or triangle, whereby the spray patterns of each of the flow distances do not substantially overlap. The spray head has substantially no moving parts and can be formed by computer printing. The invention also relates to a spray head assembly and a method of deicing a surface with deicing or snow melting fluid.

Abstract: A method and system for distributing a fluid onto a selected surface having a sprinkler system with a sprinkler head; pumps and piping for distributing the fluid through the sprinkler system; where the sprinkler system has a first and second aperture and where the dispensing fluid for winter application includes calcium acetate or potassium acetate.
