|Stratum VRS system
Stratum VRS system
STRATUM VRS SYSTEM — Vacuum Release System (VRS) monitors pump suction, turns off power, and vents suction to atmosphere when a blockage is detected. Certified and fully compliant with the VGB Pool and Spa Safety Act. Capable of monitoring single speed and dual speed pump suction lines. Complete internal system test adjusts to current operational parameters prior to entering monitoring phase of the program. Automatic restart after certain activations. Designed for use with single phase pumps up to 3 HP. Larger pumps and 3 phase power require purchase of external pump contactor. Includes 7 day programmable timer. 115 VAC (up to 1 HP) or 208/230 VAC (up to 3 HP). ETL Listed. Complies with ASTM F23887-04 and ASME 112.19.17.
VAC-ALERT - Safety Vacuum Release System (SVRS)
The Vac-Alert Model VA-2000L is a Safety Vacuum Release System (SVRS) designed for suction lift applications. Suction lift in this case applies to all applications where the circulating pump suction is either at or above the level of the pool water surface. This unit incorporates a 0.170" diameter orifice opening installed below the surge tube section. This orifice opening is sized to prevent nuisance tripping of the SVRS unit caused by high vacuum surges typical of many pump start-up conditions. The Model VA-2000L SVRS unit also utilizes a check valve assembly equipped with a 3.5 pound spring, a poppet disc and a one-way (up only) vented poppet This check valve assembly permits continued water flow to the circulating pump while the SVRS unit is in the open or vented position. The 3.5 pound spring further compressed by the poppet disc, creates enough sealing force within the check valve to allow partial water flow to the circulating pump for suction lifts up to 3.5 feet. This is critical to the elimination of circulating pump damage that can be caused by a sustained dry-running condition. The one-way vented poppet allows the surge chamber to be internally recharged when the circulating pump is turned off.
VAC-ALERT (SUBMERGED) — The Vac-Alert - Submerged is a Safety Vacuum Release System (SVRS) designed for submerged suction applications. Submerged suction in this case applies to all applications where the circulating pump suction is below the level of the pool water surface. This unit incorporates a 0.375” diameter orifice opening installed below the surge tube section. This orifice opening is sized to provide a limited amount of pump start-up surge protection, while at the same time allowing enough air into the piping system to insure dissipation of the dynamic suction force caused by the circulating pump.
It also utilizes a check valve assembly equipped with a 0.25 pound spring and a non-vented poppet (no poppet disc or hole through the poppet). This check valve assembly utilizes a light duty spring to minimize the sealing force of the check valve. The non-vented poppet insures that water from the circulating system, under a positive hydrostatic head condition, does not migrate up into the SVRS.
For pumps operating 24/7 we recommend installation of this unit (even if it's a lift application situation).
