The Hartell KL-1DG is built for demanding environments where space is limited, temperatures run high, and reliability matters. Here’s where this low profile pump truly shines:

• HVAC Units (Residential & Commercial)
  From home HVAC units to commercial rooftop systems, this pump removes hot condensate quickly to help prevent overflows, leaks, and equipment stress. This is especially useful in retrofits or builds where space under the unit is tight.

• Ceiling Cassette and Ductless Mini-Split Systems
  These compact HVAC systems are often installed in tight ceiling spaces or on walls where standard condensate pumps won’t fit. The KL-1DG’s low-profile form factor makes it perfect for concealed installations without sacrificing performance.

• Refrigeration Units
  In walk-in coolers, display fridges, or cold rooms, condensate needs to be removed quickly and efficiently. The KL-1DG prevents pooling water and ice buildup, protecting both equipment and products.

• Humidity Control Systems
  Dehumidifiers and air handling units in environments like data centers, hospitals, or indoor grow rooms can generate significant condensate. The KL-1DG handles continuous loads without failure, maintaining optimal moisture control.

• High-Temperature Boiler Applications
  Boilers, especially in commercial or industrial settings, produce extremely hot condensate. With a heat rating of 100°C (212°F), the KL-1DG is built to safely remove hot condensate in systems where standard pumps fall short.

If you’re working in tight quarters but still need serious performance, the KL-1DG delivers. We offer the smartest solution for pros who need a space-saving, high-temperature condensate pump they can trust.
