The SPR-2000™ programmable fluid controller* Controls with electronic precision and consistency how much fluid flows to one or more of these Unist systems: Uni-Roller® Type S, TSL™ System, Mini-Roller™, Powered Uni-Roller® and/or Low Volume Spray Nozzles.
The automatic lubrication system intermittently actuates a bank of fluid Solenoid Valves (up to 22 outputs) that dispense a programmed quantity of fluid to specific lube points. The valve actuation on this electronic fluid dispenser is determined by production line rates so there is no under or over lubrication whether it is a stamping press or roll forming operation.
On average, a Unist automatic lubrication system can reduce stamping fluid consumption by 50% with some customers reporting reductions as high as 90%!
The SPR-2000™ 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 on this electronic fluid dispenser.
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.
Provides programmable control for the following applications/Unist systems:
That's what many of our customers report. By applying the proper amount of fluid, the combination of an SPR-2000™ 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.
Pressure switch monitors for low fluid pressure.
Press Control Interface allows SPR-2000™ to interface with standard press controllers.
Flow sensors monitor each valve to verify fluid flow when actuated.
Adjustable stand facilitates convenient, vibration-free mounting.
