We require a pump pressure test system capable of handling maximum pressure of 725psi (50 bars) with 1/2" NPT pressure hose connection. The unit should have 3.6 gallons tank capacity and operate within maximum temperature of 50°C (120°F). Required specifications include piston volume of 2.3 cubic inches, dimensions 28"x8.5"x9.5", and weight under 14lbs. Please provide RIGID Model 50557 (Catalogue 1450). Looking to purchase 2 units for leak detection in heating, potable water, fire sprinkler, compressed air, small bore pipe lines, and oil systems.

We require air handling units with G4, F7, and H13 filters in series configuration.  
Two units needed:  
1. 14,000 m3/h airflow capacity  
2. 21,000 m3/h airflow capacity  

Chilled water units required with capacities:  
1. 90 kW cooling capacity  
2. 105 kW cooling capacity  

Potential substitution of chilled water units with condensing units is acceptable.  
All equipment must meet specified technical parameters.

We require two air handling units with specific configurations:
1. First unit: 14000 m3/h airflow capacity with G4, F7 and H13 filters in series
2. Second unit: 21000 m3/h airflow capacity with same filter configuration

Simultaneously need two chilled water units:
1. First unit: 90 kW cooling capacity
2. Second unit: 105 kW cooling capacity

Potential consideration for condensation units as alternative to chilled water units. Please provide technical specifications and compliance certifications for all components.
