Packaged rooftop air conditioners
from Walter Meier (Climate UK) are
sad to combine high efficiency and
performance with low life cycle costs,
ease of installation and competitive
pricing. They can be configured to
meet heating, cooling and air
handling duties, reducing total plant
requirements as a result. Included are
Lambda Echos and Gamma units,
both made by Blue Box.

Optimised for use with refrigerant
R410A, Lambda Echos units have
cooling capacities from 54.4 to
327.9kW, heating capacities from 56.1
to 337.1kW and can be configured to
provide free cooling, free heating and
heat recovery to minimise energy use.

For use with R407C, the smaller
Gamma units offer nominal cooling
capacities from 5.6 to 66kW; nominal
heating capacities from 5.9 to 68.4kW.
