Introduction

Mixing and distribution manifold with thermostatic head.
The R557F allows distribution of fluid in the circuits for a predetermined temperature of exercise. This can be set with thermostatic head R462L. The flow manifold is equipped with micrometer holders with memory mechanics for the balancing of the circuits. This kit does not include: - circulator and K373 safety thermostat.
