Perfect for Undercounters
and Reach-in Applications

61%of reduction on
the environmental impact due
to CO2 emissions

Embraco Smart Drop-inThe right tool to leverage migration from fixed tovariable speed technology

Tests in application to evaluate the Smart Drop In (SDI) solution performance compared toalternative technologies.

What’s Smart Drop-in
Smart Drop-in is a solution to deploy Variable
Speed Compressors with On-Off Thermostats.
On-OffThermostat• Easy replacement of On-Off compressor• Easy development of new applications - only 1parameter can fit many application sizes and forenergy optimization• No need of high-priced thermostats for someapplications.
• Fast reaction to Thermal Load variation Optimization
for Climate Class Ranges
