The economically priced SPR-2000 JR™ programmable fluid controller keeps costs down when only two outputs are required. The SPR-2000 JR™ controls fluid flow to one of these Unist systems: Uni-Roller® Type S (up to 18in. wide), Mini-Roller™, Powered Uni-Roller® (up to 18in. wide) and/or Low Volume Spray Nozzles (1 or 2 nozzles).
The system intermittently actuates two fluid solenoid valves that dispense the required quantity of fluid to two specific lube points. The valve actuation is determined by production line rates so there is no under or over lubrication whether it is a stamping press or continuous speed operation such as roll forming.
On average, a Unist system can reduce stamping fluid consumption by 50% with some customers reporting reductions as high as 90%!
The SPR-2000 JR™ provides full-featured monitoring of critical parameters such as fluid level, pressure and flow (optional sensors are required) and alerts users with an audible alarm and red LED. An external alarm relay can also be wired directly to a press control.
Provides password-protected access to the system's setting.
prompts the user for job specifications and automatically creates a new setup (program) for Uni-Roller® applications.
allows the user to modify current setups and program spray nozzles or otehr auxillary functions.
allows the user to monitor critical system functions.
That's what many of our customers report. By applying the proper amount of fluid, the combination of an SPR-2000 JR™ controller and Uni-Roller® lubricator uses 50 to 90% less lubricant. Plus it decreases the mess, the parts cleaning, fluid recycling and costs associated with in-die spray systems, rag technology and externally lubricated rollers.
Flow sensors monitor each valve to verify fluid flow when actuated.
Adjustable stand facilitates convenient, vibration-free mounting.
