SP Units


Utilizing our proven medium pressure lamp technology, the SP-type UV systems offer a high quality 'high specifications' product at a very competitive price. Suitable for all pools and whirlpools with flows from 100-3400 gpm and flange sizes from 2"-14".


Treatment Chamber
UV treatment chambers are designed for installation into the pipe work after the filters and heaters, but before any chemical closing. Please refer to the SP Units Technical Specifications document for chamber dimensions and clearance requirements. The UV chamber is manufactured from polished 316L stainless steel and is flanged with ANSI 150 RF flanges for easy installation. Temperature probes, UV monitor probes, and automatic quartz wipers are all included.


Pressure ratings on the unit are 150psi, and pressure drop across the unit is minimal.


Control System
The control system is located in a NEMA 12 (IP54) rated panel. (see picture)


As a standard, it is supplied with a 15' cable for connection to the treatment chamber.


The power supply (PSU) and control cabinet is powered with the latest SPECTRA microprocessor control unit. Three levels of operation (simple control, full parameter display, and operator configuration) allow easy, uncomplicated operation of the unit by an operator. Included is a sophisticated password protected engineering section for integrating the unit with other system devices.


Autopower restart, pump and valve interfaces, process interrupt and low power overnight operation are all features specifically designed for use on swimming pools and waterparks.




SP Units- Designed to be the Best


The treatment chamber has been designed for the simplest installation into any pipe work system. The compact design allows existing facilities to be easily upgraded with minimum site work.






ETS's new wiper assembly now includes many unique features, making this a state-of-the-art wiper system. (see picture)
Unique double seal and bearing housing for longer life, including food-grade-approved seal materials.
Fully enclosed housing to maintain NEMA (IP) ratings.
Wiper power supply @ 24 Volt DC for improved safety.
Belt drive with all pulleys and shafts square-machined to prevent slippage and pin shearing.
Direct shaft encoding for positional location; no need for external proximity switches and internally  located magnets. No complex transfer gear boxes for limit switches.
Wiper interval operator selectable, with an optional override switch.
Ability to upgrade most systems with a retrofit wiper.




The new electronic control system features an automatic start-up/commissioning application. Operators do not need to position the wiper carriage. A very simple commissioning procedure records the wiper position at both ends of the chamber and establishes its travel run without the need to check stop positions and adjust limits accordingly. There is no risk of proxy faults causing wiper failure. The system also fully recovers from power dips and interruptions, with a permanent memory of wiper location and travel direction stored in its processor. The wiper can also report directly into the new SPECTRA control panel for fault reporting and data logging.
