DAIKIN GAS TIGHT JOINT (DGT)
DGT is a non-brazed connection for Refrigerant piping. Pipes can be joined easily and quickly without brazing or using any special tools. It meets the stringent requirements in terms of safety and leak tightness while providing substantial benefits.
WHY BUY DGT?
|Daikin DGT||Other Brands|
|FITTING||✓ Only needs 1 Joint for Tight seal||Requires additional accessories (i.e. inserts and joints) for stable fit|
|SPECIAL TOOLS||✓ N/A = $0 hidden costs||Require specialised crimping tools costing from S$3,000 onwards|
✓ Double Protection with V-seal and Dual O-Ring to effectively minimise leakage.
✓ Ensures tight seal and prevents condensation forming inside
Single O-Ring only
|Precision Piping Method (PPM)||✓ Enhanced productivity with prefabrication of piping into modular form for easy connection||No such service|
|CERTIFICATION||✓ First to be Awarded 3 Ticks Excellent Rating by Singapore Green Building Council (SGBC) Certification||Not Certified under SGBC|
By the unique double sealing method, the sealing performance is secured over a long period even under severe conditions such as pressure of 4.3MPa during temperature of – (minus) 45 degree C through + (plus) 130 degree C.
DURABLE FOR HIGH PRESSURE
By leverage method, the pull-out resistance is more than 4 times (17.2MPa) of the max. operating pressure.
The installation is completed using low torque tightening method with just one or two turns of the nut. Regular wrenches or spanners are used without any special tools required, making installation easy even when operating space is limited.
FIRE FREE CONNECTION (SAFETY FIRST)
Neither nitrogen gas replacement nor fire prevention cure is required. The time for installation is shortened and the total cost is reduced. The installation quality is much more stable compared with a brazing method.
With double sealing, made up of O-ring and V-seal, it prevents refrigerant from escaping. This eliminates the hassle of brazing at job site with labour intensive requirements.
REDUCE CONDENSATION CONCERNS
A combination of rubber packing and screwed metal body offers gas-tight and rigid connection without brazing.
