Product Description

1. Core Performance Features: Why Choose the EK Series?

(1) Triple-Action Protection

The EK Series doesn’t just filter particles—it actively purifies the refrigerant:

Moisture Removal: Prevents “freezing” at expansion valves and stops hydrolysis of POE oils.
Acid Neutralization: Captures acidic by-products generated during compressor burnout, protecting motor windings from copper plating.
Solid Contaminant Filtration: Traps brazing slag, debris, and compressor wear particles (with a precision of 20 microns).

(2) Rugged Construction for Harsh Environments

Heavy-Duty Steel Shell: Withstands high mechanical stress and vibration in transport refrigeration or industrial applications.
High-Pressure Rating: Rated for 47 bar, ensuring safe operation in high‑temperature environments and with R410A systems.
Corrosion Protection: The epoxy coating ensures long‑term durability even in salty or humid coastal conditions.

(3) Universal Replacement & Easy Installation

Direct Interchangeability: Physical dimensions and connection sizes are designed for direct replacement of Emerson/Vilter EK series, Alco, and Sporlan standard models.
Dual‑Connection Options: SAE flare connections allow quick wrench installation for the after‑market, while ODF solder connections provide a permanent, leak‑proof solution for OEM assembly.
Capacity Coding: Model numbers (e.g., 083, 163, 303) represent the core volume in cubic inches, making selection straightforward.

2. Application & Selection Guide

Application Scenario	Recommended Models	Reason for Selection
Commercial Refrigeration (Supermarket parallel racks, freezers)	EK-083, EK-084, EK-163	Medium‑to‑high‑capacity models suitable for R404A/R507 systems.
Condensing Units / Parallel Rack Systems	EK-164, EK-165, EK-303	High flow rate with low pressure drop.
Air Conditioning Systems (Chillers, VRF, Roof‑top units)	EK-084S, EK-164S	ODF solder connections for vibration‑resistant installation.
Burn‑out Recovery (Post‑compressor‑failure system cleanup)	EK-163, EK-303	High acid‑adsorption capacity to protect the system.
Light Commercial (Beverage coolers, small AC units)	EK-032, EK-033, EK-052	Compact size, easy to install in tight spaces.
