Man. Cooperative Engineering and Contracting Service on Heating Systems--Seventy. years' experi ence in piping installation puts Grinnell Company, Inc., in an especially advantageous position to render service of the highest order to heating engineers and their clients. This not only includes a cooperative advisory service which is frequently used by engineers who - desire authoritative practical infor mation when working on problems more or less out of the ordinary, but also a complete and expert contracting-service as well. Close'contact with power and industrial piping enables Grinnell Engineers to approach questions of heating with full realization of their relationship to other factors. In formation supplied by members of the Grinnell Staff regarding the utilization of waste heat through the agency of hot water systems, the utilization of exhaust steam, etc., has proved of invaluable assistance in working out more efficient heating. Grinnell Engineering or Con- . tracting Service is equally satis-' factory on the remodeling of old heating systems--a type of work with which the Company is thor oughly familiar. A Revolu tionary Developmen t in Forced Hot Water Heating-- One of the chief difficulties in the way of a broader use of forced hot water heating systems with their many important advantages has been the determination of pipe sizes by the complex and arduous method of calculating frictional re sistances. Failure to do this, plus easily possible installation mistakes has resulted in many unsatisfactory installations of this type of heating system. This whole complication has now been simplified by the invention of the Grinnell Equiflo Valve. The Grinnell Equifto Valve for forced hot water heating permits: 1. The calculation of pipe sizes for this system by simple tables, similar to those commonly used in connection with the design of vacuum steam systems. 2. Change in locations of radiators or piping during installation to take care of local construction conditions without recalculation of pipe sizes. 513 y
