We report on magnetothermodynamic properties of single crystal KEr(MoO_4)_2 which were investigated from nominally 0.4 K to 20 K in magnetic fields up to 4 T. Using the available specific heat data the diagram of temperature and magnetic field dependence of the total entropy was constructed. Predictions for temperature dependences of the relative temperature variations during the adiabatic demagnetization and the entropy variation during the isothermal demagnetization were calculated from the specific heat data. The obtained results suggest that unlike common refrigerants, in KEr(MoO_4)_2 the quantities describing magnetic cooling remain nearly constant in the temperature range 2-10 K.
