The ARO Hartell Series KL1DG low profile condensate pump is engineered for restricted installation spaces.
Its slim design allows for easy installation in walls, ceilings, and shallow equipment areas.

This pump handles hot condensate up to 100 °C (212 °F) without performance loss.
It supports continuous operation in critical cooling zones such as data centers and commercial buildings.

The quiet motor design makes it suitable for offices, retail areas, and noise-sensitive environments.
An integrated auxiliary safety switch helps prevent overflow and protects connected equipment.

The KL1DG is built using durable, heat-resistant materials.
This ensures long service life and stable operation under demanding conditions.

The low profile body saves valuable installation space.
This makes the pump ideal for retrofits and compact system designs.

The high-temperature capability allows safe condensate removal from boilers and high-heat HVAC systems.
Many standard pumps cannot handle these temperature levels.

Quiet and efficient operation improves comfort in occupied spaces.
This reduces noise complaints and supports professional installations.

The continuous-duty motor provides reliable performance.
It is designed for long operating cycles without frequent maintenance.

“ARO’s Ideal Commercial Grade Solution for Restricted Installation Spaces”

The ARO Hartell Series KL1DG low profile condensate pump is used in residential and commercial HVAC systems.
It helps prevent leaks, overflows, and equipment stress in tight installation spaces.

Ceiling cassette and ductless mini‑split systems benefit from its compact footprint.
The low profile design allows discreet installation in ceilings and wall cavities.

In refrigeration units, the KL1DG removes condensate efficiently.
This reduces water pooling and ice buildup around sensitive equipment.

The pump is also well suited for data center applications.
It supports continuous condensate removal in critical cooling zones, helping protect IT infrastructure and maintain uptime.

Humidity control systems in data centers and hospitals rely on stable, uninterrupted operation.
The KL1DG handles continuous loads and elevated temperatures without failure.

High‑temperature boiler applications require safe condensate management.
With a 100 °C (212 °F) rating, the KL1DG performs where standard pumps fall short.
