JORC SMART-GUARD Level Sensing Condensate Drain Valves Explained

On-demand draining · Up to 725 PSI · Alarm notifications · Covers systems up to 3,500 CFM

⚠️

Are Your Timer Drains Costing You?

Timer-controlled drains open on a fixed schedule, blowing out compressed air even if there's no condensate to remove. Level-sensing drains only open when liquid is actually present, eliminating unnecessary air loss and reducing wear. If your system runs variable loads, the switch pays for itself fast.

SMART-GUARD-HP: For High Pressure Systems

Handles up to 725 PSI · Works up to 3,500 CFM compressed air systems

When to choose the HP model:

  • System operating pressure above 230 PSI
  • Large industrial compressors (up to 3,500 CFM)
  • High condensate volumes: handles 31 gal/hr
  • Applications where standard drains have failed under pressure

SMART-GUARD-MINI-AL: Compact Drain with Alarm Output

12 gal/hr · 230 PSI max · Dual DIN connectors · Ideal for dryers and filters

How the dual DIN connections work:

TOP
Power Input: Connect to your 24V DC or 110/230V AC power supply via DIN 43650 Form B
BOT
Alarm Output: Wire to your external alarm, PLC, or monitoring panel

When does the alarm fire?

Alarm triggers after 100+ consecutive valve openings without stopping.

This signals one of two problems:

  • Debris clogging the valve (clean or replace)
  • Condensate load exceeding the drain's capacity (upgrade needed)
💡 Best fit: Refrigerated air dryers and compressed air filter housings. The mini footprint installs where full-size drains won't.

🔧 Standard Features: Every SMART-GUARD Model

🔌

Dual DIN 43650 Form B Connectors

Industry-standard plug-in connections for fast, tool-free wiring

🪣

Built-In Mesh Strainer

Catches debris before it reaches the valve seat, extending service life

💡

LED Status Indicator

Instantly shows power status and valve activity, no tools needed to check operation

🧪

Manual Test Button

Force-open the valve to verify operation during commissioning or routine checks

📊

Level-Sensing Drain Logic (vs. Timer Drains)

Opens only when condensate reaches the sensor, not on a timer. Result: no wasted compressed air between drain cycles, and no condensate overflow if production rates spike unexpectedly.

🗓️ Maintenance Schedule: Quick Reference

🧹

Periodic

Clean the mesh strainer. Frequency depends on air quality and condensate load. Inspect when flow seems reduced.

🔍

Annual (Minimum)

Full inspection of valve operation, connections, and seals. Use the manual test button to confirm proper open/close function.

🛠️

As Needed

Service kits available for both SMART-GUARD and SMART-GUARD-MINI series. Kits include housing gaskets and valve replacement components.

✅ Pro tip: Keep a service kit on-site. Swapping gaskets during planned downtime is far cheaper than emergency service on a leaking drain.
🚨

Troubleshooting: Common Issues & Fixes

🔴 Drain is cycling too frequently / MINI-AL alarm is active
Likely causes:
  • Condensate load exceeds rated capacity (12 gal/hr for MINI-AL): consider upgrading to a full-size SMART-GUARD
  • Debris lodged in valve or strainer causing partial blockage: clean or replace strainer
🔴 Valve not draining / condensate backing up
Check in order:
  1. Press the manual test button. If valve opens, power and control are working; issue is sensor or strainer
  2. Inspect and clean the mesh strainer (most common cause)
  3. Confirm operating pressure is within rated range for your model
  4. If LED is off, verify power supply voltage and DIN connector seating
🔴 Valve leaks when closed
Seat contamination or damaged seals are the most likely cause. Use a service kit to replace housing gaskets and valve internals. If leaking continues after a service kit, replace the valve unit.
🔴 HP model not performing at high pressure
Verify the pressure rating. SMART-GUARD-HP model is rated to 725 PSI, the standard SMART-GUARD is only rated to 230 PSI. Exceeding ratings can cause seal failure and erratic operation. Also confirm pipe sizing matches flow requirements at rated pressure.
