The Dual Vertical Series Non-JIC reservoirs incorporate a rectangular body and a flat bottom that extends past the reservoir body to serve as the mounting surface of the reservoir. An internal baffle divides the reservoir into two chambers but has open areas above and through the baffle for circulation between chambers. Designed to accept an independent cover for each reservoir chamber. Standard Features: Reservoir capacities of 40, 50 and 60 gallons Partial height baffle divides reservoir into two equal size chambers and has cut outs for circulation Two Channel gaskets installed Cover plates are sold separately, refer to Cover Series 2 or 3 for available options (two covers per reservoir are required) Reservoir bottom is flat (1) 3/4 inch NPT drain (plugged) Exterior painted with a LDI gray primer Interior coated with rust preventative oil 5 inch back mount GT623 Series sight gauge Card thermometer, dual scale 0°F to 220°F and -20°C to 110°C Sight gauge and hardware to mount a cover provided loose with reservoir Temperature Rating: Industry accepted design practice for hydraulic systems limits maximum operating temperature to 180° F (82° C), but materials used for fabrication of the reservoirs are capable of operating between -40° and 212° F (-40° and 100° C). Caution: Reservoirs are not designed for internal positive or negative pressure applications. For these applications, consult the factory.
