Universal AutoSync

 

The Universal AutoSync is a unique sequencing product only available from Standard Pneumatic Products. Unlike other sequencers which simply have the compressors "take turns", the AutoSync automatically swaps dual compressor lead and lag mode to any cycle time you choose. Standard swap cycle is anywhere from 10 minutes to 7 days, with full manual override for compressor maintenance on either compressor.

Controller Dimensions 6" X 6" X 4" DP

Optional Features:

Multiple Lead/Lag Compressor Control:

Manual 2 or 3 Compressor Control- Manual Switching between two or three AutoDual Controllers/Compressors.

Automatic Lead/Lag Switching - Available for 2 Compressor systems, Automatic lead compressor cycle switching (user selectable from 10min to 7 Days). Lag compressor automatically cycles to provide additional air under high load conditions, with full AutoDual functionality (2 Autoduals required). Includes manual override to hold either compressor in lead or lag mode.

Automatic Time-of-Day Start/Stop - Internal clock timer mounted inside ADS size enclosure, automatically turns compressors ON in the morning and OFF in the evening. Available for all single or dual compressor systems. Day-of-week adjustable for daily or weekend usage. Full manual override. Can be configured to AUTOMATICALLY drain plant air lines and system upon evening shutdown (required by law in some states)

Autodual Simplex Lead/Lag Controller Simplex controller runs two compressors in Lead/Lag mode with ONE Autodual controller. No control connection required between units. Ideal solution for Intellysis or "T" control units. Incorporates full Autodual functionality on second compressor only, yet  gives lead/lag functionality to both compressors. Manual and full automatic/manual switching available.

Safety:

Emergency Shutdown - External 6' Power cord connects to any non-powered normally closed (N.C.) emergency shutdown device, i.e., low oil pressure, low oil level, high air temperature, power line monitors, starter overload, or any of the above combinations. Failure of any of the above shuts the compressor motor down 20 seconds after receiving fault signal, activating flashing light on the Universal AutoDual.

Remote Shutdown Signal- Sends a remote fault signal (24VDC, 40ma) from AutoDual to a control room sensor,  or auxiliary remote audible or visual alarm.

Oil Pressure Switch - Din Mounted Low Oil pressure switch (10 P.S.I) triggers AutoDual Emergency Shutdown feature in low oil pressure condition.

Automatic Tank Maintenance:

Timed Tank Drain - Activates tank mounted solenoid drain for 5 seconds for every hour of compressor pumping time. Motor idle time does not affect the drain timer, saving energy and wasted air.

Energy Savings

The Universal AutoDual ® is so effective it typically allows end users to recover the capital outlay of their entire compressor purchase within 3 years in energy savings alone. Here's how we do it:

Example:  A savings analysis of a 25 HP, 2 stage, reciprocating or rotary screw compressor operating a factory that is producing 7 days per week on three shifts (8760 hours per year).

Basis
25 HP = 23 KW x motor P.F. of 1.15 (power factor) = 26.45 KW
Unloaded KW = Full Load KW  (26.45KW) x
Unloaded KW (25%) x losses (part load motor efficiency
& power factor = 35% efficiency loss
Unloaded KW = 26.45 x 25 = 10.17KW 
     .65
1st Shift: 75% Loaded, 25% Unloaded
2nd Shift: 40% Loaded, 60% Unloaded
3rd Shift: 20% Loaded, 80% Unloaded
Electric Rate:  $.10/KWH
Unloaded kW: 25% of Full Load = 10.17KW at
8760 hours per year

Total Annual Electric Energy Savings = 49,000 KwHrs/year

Unloaded kW Savings
1st Shift:  2920 hours x .25 x 10.17 x .10 = $743
 2nd Shift: 2920 hours x .60 x 10.17 x .10 = $1782
   3rd Shift:  2920 hours x .80 x  10.17 x .10 = $2375 Total Annual Power Savings:  $4900**

**In areas of higher KWH rates, such as Metro New York, at 0.15/KWH, the annual savings would be $ 7350.00/yr.

Consider this quote directly from the COMPRESSED AIR CHALLENGE,

"Compressed air is not typically viewed as a cost of production—but it is anything but “free.” The generation of compressed air requires a huge amount of energy—and a piecemeal approach to building a compressed air system serves to worsen the problem through leaks, mismatched supply/demand, and inappropriate uses. The result is unreliability, energy waste, reduced productivity, and higher operating costs."
