Product Introduction

The size-15 cabinet expands fan and recovery capacity for medium controlled suites while keeping a horizontal ceiling-mounted profile. Twin counterflow modules and an approximately 217 kg component mass distinguish this model from the compact size-10 unit and require a correspondingly stronger suspension layout.

Key Features

Medium suite capacity

The larger fan modules support a shared ventilation stream for several rooms or one medium controlled space.

Twin recovery-core layout

Two counterflow modules provide the heat-transfer area required within a low-height cabinet.

Ceiling-access maintenance

Filters, fans and recovery sections can be approached from the designated service face without occupying floor plant space.

Applications

Medium laboratory suites, controlled preparation areas, clean support departments and grouped rooms requiring balanced ceiling ventilation.

Solutions for Your Application

One compact ceiling unit cannot provide the combined airflow for several rooms.Use the size-15 fan and recovery package around the balanced 1500 m3/h system schedule.

The heavier cabinet must remain safely serviceable above the ceiling.Provide independent structural hangers and a removable access zone sized for filters and recovery modules.

Available Options

Heating coil, filter classes, condensate arrangement, frost protection, airflow sensors, remote control and duct connection direction can be selected.
